Michael Heinekey, Department of Chemistry, University of Washington is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program for continued explorations of metal-dihydrogen interactions or metal-alkane interactions. He uses unique NMR techniques including photolysis of precursors in the NMR probe; very low temperature NMR, exchange coupling and tritium NMR to explore the nature of these weak bonds. Heinekey also studies elongated dihydrogen complexes which display novel vibrational and dynamic properties that may provide a "snapshot" of an H-H bond rupture process. The education and training of future scientists and the development of new NMR methods are major impacts of this work. The activation of hydrogen is a critical reaction biologically (hydrogenase enzymes) and industrially. By better understanding how various metal species interact with hydrogen, better homogeneous catalysts and processes may be designed.

华盛顿大学化学系的Michael Heinekey得到了无机，生物无机和有机化学计划的支持，继续探索金属-二氢相互作用或金属-烷烃相互作用。他使用独特的NMR技术，包括NMR探针中前体的光解;极低温NMR，交换耦合和氚NMR来探索这些弱键的性质。海涅基还研究了伸长的二氢复合物，它显示出新的振动和动力学性质，可以提供H-H键断裂过程的“快照”。未来科学家的教育和培训以及新NMR方法的开发是这项工作的主要影响。氢的活化是生物学（氢化酶）和工业上的关键反应。通过更好地理解各种金属物质如何与氢相互作用，可以设计更好的均相催化剂和工艺。
