Dr. Phyllis Leber and
Dr. John Baldwin, Distinguished Professor of Chemistry and William Rand Kenan, Jr. Professor of Science at Syracuse University, have been collaborating since the summer of 2000. Although the focus of their research has been the elucidation of the mechanism of the [1,3] sigmatropic rearrangement of vinylcyclobutanes, they have also conducted mechanistic studies involving [1,5] hydrogen shifts and cyclobutene electrocyclic ring openings. In all of these cases the aim of collaboration is to understand the extent and limits of application of the Woodward-Hoffman theory of conservation of orbital symmetry. Our collaborative efforts suggest that the vinylcyclobutane rearrangement traverses a shallow potential energy surface that yields a short-lived diradical intermediate. To date, the collaboration has yielded a total of 14 publications including two review articles. A total of 15 students have appeared as coauthors on 10 of these publications.\n\n

My collaboration with Dr. Morten Andersen from ETH Zurich grew from his interest in using isotope geochemistry to better understand Earth system processes at the Earth's surface. His particular interest involves global U cycling and the unique 238U/235U ratio that develops as a response to changes in the amount of ocean oxygenation. I have a long-standing interest in U geochemistry and was able to share with him a selection of marine sediment samples for analysis. I have enjoyed the opportunity to work with Dr. Andersen on the interpretation of his results.

Dr. David Hastings and I belonged to the same graduate group at the University of Washington, where we both focused on redox sensitive trace metals. I was very interested in the recent research he was doing at Eckerd College in Florida in response to the Deep Water Horizon oil spill in the Gulf of Mexico. I have enjoyed the opportunity to work with Dr. Hastings on the interpretation of changes in trace metal concentrations in sediment cores from the Gulf of Mexico.

My collaboration with Dr. Bill Martin began when I was a post doctoral scholar at the Woods Hole Oceanographic Institution (November 2000 – October 2002). I worked extensively with Bill to study the controls on trace metal mobility in the environment, particularly in coastal areas off Massachusetts.
\n\n
Fieldwork is incredibly labor intensive and continues from the time the samples arrive (often in the early afternoon for coastal work) until the sampling is completed (often in the early hours of the next morning). Because we do not want conditions in the sediment cores to change prior to sampling, we endeavor to keep the samples under conditions similar to their in situ conditions, which means sampling in a cold room at 4°C and working with samples in large nitrogen-filled glove bags. Analyses, which are time sensitive, must then be completed the following day. I have been fortunate to have several F&M undergraduates (Melissa Reinard '03, Sarah Gallagher '04, Gloria Yen '06 and Elizabeth Herrle '06) accompany me to Woods Hole and assist in supply preparation, sampling and analysis. Gloria also returned to WHOI with me to use the ICP-MS facility for sample analyses.

My collaboration with Dr. Yoder grew from a shared interest in metal-organic interactions. Dr. Yoder had previously provided assistance to one of my earlier research students (Kelly Murphy, class of 2009) who was working on molybdenum complexation with small organic molecules. However, Kelly encountered difficulties in using 95Mo NMR to understand the structural details of the complexes that were forming. My initial collaboration with Emily Christie (class of 2015) during Summer 2012 on a different project transitioned into co-mentoring with Dr. Yoder during Summer 2013. During that summer and the following academic year, Emily was able to complete the detailed work that was required to understand how 95Mo NMR might help in understanding the intricacies of Mo-organic complexes.

Professor Yoder collaborates with Dr. Jill D. Pasteris in the Department of Earth and Planetary Sciences at Washington University, St. Louis, MO . Their research involves the structure and stability of compounds in the apatite family of minerals. Calcium hydroxy apatite, the major constituent of bone and teeth, serves as a prototype for the study of the substitution of carbonate and other anions for the phosphate and hydroxide ions. The study should lead to a better understanding of the effect of carbonate and other anions on the solubility and structure of apatites.

History of the 40 Year Partnership
\n\n
A unique and extensive research collaboration between Professors Claude H. Yoder, Charles A. Dana Professor of Chemistry at Franklin & Marshall College, and Charles D. Schaeffer Jr., retired A.C. Baugher Professor of Chemistry at Elizabethtown College, began in November, 1966. Claude Yoder had been recently hired as assistant professor and Schaeffer was enrolled in his laboratory section of general chemistry. Yoder gave him a simple project at the conclusion of lab and Schaeffer remembers: “I was asked to filter this beautiful moisture-sensitive, purple solid. So, beaming with pride and using my best freshman chemistry technique, I checked out brand new glassware from the stockroom, set up the filtration system, turned on the suction, moistened the filter paper with distilled water to make a good seal, added the solid, and, of course, promptly destroyed it. Luckily, Yoder had not entrusted the entire supply of the sample to a lowly freshman!”
\n\n
In the summer of 1970 Schaeffer headed for graduate school at the Albany campus of the State University of New York. The first graduate faculty member that Schaeffer encountered was Professor Jerold J. Zuckerman, who had served as the graduate mentor for Yoder several years earlier and who had recently relocated to Albany with his graduate students and postdocs. Zuckerman served as Schaeffer’s Ph.D. advisor for the next four years. This was an especially productive time for a collaboration between the three that led to a number of jointly authored papers, but, more importantly, to a life-long interest in inorganic chemistry and to application of nuclear magnetic resonance (NMR) spectroscopy to the solution of structural and dynamic problems.
\n\n
Schaeffer completed graduate school at Albany in 1974, was hired at Elizabethtown College (only 15 miles from F&M) in 1976, and the strong ties of the Yoder-Schaeffer collaboration were renewed. Their research collaboration has yielded both short- and long-term benefits to the two investigators and to their students.
\n\n
\n\t- Nineteen papers carrying the names of student investigators appear in scientific journals.
\n
\n\n
\n\t- F&M and Elizabethtown student presenters are well-represented at regional and national meetings, communicating their work in oral or poster form.
\n
\n\n
Yoder and Schaeffer have collaborated on a successful undergraduate textbook on the subject, as well as on other projects relating NMR to both research and teaching.

利伯-鲍德温合作

Phyllis Leber博士和雪城大学杰出化学教授John Baldwin博士以及科学教授William Rand Kenan Jr.自2000年夏天以来一直在合作。虽然他们的研究重点是阐明乙烯基环丁烷[1,3]异位重排的机理，但他们也进行了涉及[1,5]氢位移和环丁烯电环开环的机理研究。在所有这些情况下，合作的目的是了解Woodward-Hoffman轨道对称守恒理论的应用范围和局限性。我们的共同努力表明，乙烯基环丁烷重排穿过一个浅的势能表面，产生一个短暂的二自由基中间体。迄今为止，这项合作共发表了14篇论文，其中包括两篇综述文章。共有15名学生以合著者的身份出现在其中10份出版物上。

我与Bill Martin博士的合作始于2000年11月至2002年10月在伍兹霍尔海洋研究所做博士后时。我与比尔进行了广泛的合作，研究对环境中微量金属流动性的控制，特别是在马萨诸塞州的沿海地区。
现场工作是一项令人难以置信的劳动密集型工作，从样品到达(通常在下午早些时候进行沿海工作)一直持续到采样完成(通常在第二天凌晨)。因为我们不希望在采样前沉积物岩心的条件发生变化，所以我们努力将样品保持在与其原位条件相似的条件下，这意味着在4°C的寒冷房间中采样，并在装满氮气的大手套袋中处理样品。对时间敏感的分析必须在第二天完成。我很幸运有几位F&M的本科生(Melissa Reinard 03, Sarah Gallagher 04, Gloria Yen 06和Elizabeth Herrle 06)陪我去Woods Hole，协助供应准备、取样和分析。Gloria也和我一起回到WHOI使用ICP-MS设备进行样品分析。

我与约德博士的合作源于对金属-有机相互作用的共同兴趣。约德博士曾帮助过我早期的一个研究生(凯利·墨菲，2009届毕业生)，她当时正在研究钼与小有机分子的络合作用。然而，凯利在使用95Mo核磁共振来了解正在形成的复合物的结构细节时遇到了困难。2012年夏天，我与Emily Christie(2015届)在一个不同的项目上进行了最初的合作，2013年夏天，我与Yoder博士共同指导了这个项目。在那个夏天和接下来的学年里，艾米丽完成了所需的详细工作，以了解95Mo核磁共振如何帮助理解mo有机复合物的复杂性。

40年合作的历史
1966年11月，Franklin & Marshall学院的Charles A. Dana化学教授Claude H. Yoder和Elizabethtown学院退休的A.C. baughher化学教授Charles D. Schaeffer Jr.展开了一项独特而广泛的研究合作。克劳德·约德最近被聘为助理教授，谢弗也加入了他的普通化学实验课。在实验结束时，约德给了他一个简单的项目，舍弗记得:“我被要求过滤这种美丽的对水分敏感的紫色固体。于是，我带着自豪的笑容，用我最擅长的大一化学技巧，从储藏室里拿出全新的玻璃器皿，设置好过滤系统，打开吸盘，用蒸馏水湿润滤纸，使其密封良好，然后加入固体，当然，马上就把它毁掉了。幸运的是，约德没有把样品的全部供应委托给一个卑微的大一新生!”
1970年夏天，谢弗去了纽约州立大学奥尔巴尼分校的研究生院。谢弗遇到的第一个研究生教员是杰罗尔德·j·祖克曼教授，他几年前曾担任约德的研究生导师，最近带着他的研究生和博士后搬到了奥尔巴尼。扎克曼在接下来的四年里担任谢弗的博士导师。这是三人合作的一个特别富有成效的时期，他们共同发表了许多论文，但更重要的是，他们对无机化学产生了毕生的兴趣，并应用核磁共振(NMR)光谱来解决结构和动态问题。
1974年，谢弗在奥尔巴尼完成了研究生学业，1976年被伊丽莎白镇学院聘用(距离F&M仅15英里)，约德与谢弗的紧密合作关系得以延续。他们的研究合作为两位研究者和他们的学生带来了短期和长期的好处。
- 科学期刊上发表了19篇带有学生调查人员名字的论文。
- F&M和伊丽莎白镇的学生演讲者在地区和国家会议上都有很好的代表，他们以口头或海报的形式交流他们的工作。
Yoder和Schaeffer合作编写了一本关于该主题的成功的本科教科书，以及与核磁共振研究和教学相关的其他项目。
