Atomistic Mechanisms for Gas Phase X- +CH3Y -----> XCH3 + Y- SN2 Reactions. Dynamics With and Without X- Solvation

**Seminars begin at 4:00 PM and will be held in Clark Hall Room 101**

September 4, 2015

William Hase

This seminar will present chemical dynamics simulations, which study the motions of atoms during the course of a chemical reaction. The simulations describe how the reaction occurs at the atomistic level, identifying the fundamental reaction mechanisms.  The simulation results may be compared with those from experiment such as rate constants, the yields of different reaction products, and the energies in the reaction products. The detailed dynamics of gas phase SN2 nucleophilic substitution reactions will be discussed .1,2
