Professor Peter Wolczanski of Cornell University is supported by the Inorganic, Bioinorganic and Organometallic Chemistry program to probe the role of the density of excited electronic states in organometallic and inorganic reaction mechanisms. The hypothesis that swifter reactions characterize second row transition metal complexes relative to third row analogs due to greater d/s orbital mixing for the heavier elements is being tested. Strong field aryl ligands are being utilized as ancillary ligands to control the spin state and reactivity of first row metal complexes.The broader impacts of this project include student exposure to sophisticated techniques, both experimentally and computationally. In addition, elementary school science demonstrations and organizational lesson plans are being generated, and the roles of ethics and intellectual property issues in science today are being explored.

康奈尔大学的 Peter Wolczanski 教授在无机、生物无机和有机金属化学项目的支持下，探索激发电子态密度在有机金属和无机反应机制中的作用。 由于较重元素的 d/s 轨道混合更大，第二行过渡金属配合物相对于第三行类似物具有更快的反应，这一假设正在接受测试。强场芳基配体被用作辅助配体来控制第一行金属配合物的自旋状态和反应性。该项目的更广泛影响包括学生接触复杂的实验和计算技术。此外，正在制定小学科学演示和组织课程计划，并探讨道德和知识产权问题在当今科学中的作用。
