Abstract:

  Indistinguishable nuclei call for applications of the nuclear spin hypothesis and the proper molecular symmetry (MS) groups. This has fascinating consequences for the quantum dynamics. I shall present three examples, from the familiar H2 molecule via a methyl group to boron rotors. Such molecular rotors with identical nuclei do not allow classical molecular dynamics simulations which start out from localized states in global potential minima, and the nuclear spins block laser excitations of the rotations. The purpose of the seminar is to stimulate reflections and possibly discoveries of quantum dynamics effects of nuclear spins in your own systems of interest.

 

About the speaker:

  Professor J?rn Manz received his Ph.D. from Technische Universit?t München in 1972 (advisor: Prof. G.L. Hofacker). He did his postdoctoral research at Weizmann Institute Rehovoth with Prof. R. D. Levine (1974-1975) and at Technische Universit?t München with Prof. D. J. Diestler (1975-1976). He became Fiebiger-Professor for Theoretical Chemistry at Universit?t Würzburg in 1985, and has been a Professor for Theoretical Chemistry at Freie Universit?t Berlin since 1992. He served as the Director of Institute for Physical and Theoretical Chemistry at Freie Universit?t Berlin in 1993-1999. He was also the Referee-in-Chief of the German Research Foundation for Theoretical Chemistry in 2000-2012. From 2013, Prof. Manz has been a Guest Professor at Shanxi University, State Key Laboratory of Quantum Optics and Quantum Optics Devices, in Taiyuan, China. He is the founder of the Series of International Conferences on Femtosecond Chemistry.
