Femtochemistry: the role of alignment and orientation

Creators: Zewail, Ahmed H.

Abstract

Some aspects of alignment and orientation have been considered for femtochemistry experiments. Elementary theoretical descriptions of the time evolution of alignment and angular momenta have been discussed and related to the radial and angular parts of the potential-energy surface. Applications to ICN unimolecular dissociation, H + CO2oriented bimolecular reaction, and crossings between different potential-energy curves in alkali-metal halide reactions (M + X) are give. Emphasis is on the femtosecond dynamics of the transition-state region and the clocking of fragment separation in real time.

It is a pleasure to express my thanks to colleagues and members of my research group. In particular, the discussions I had with Professor R. Bersohn and Mr S. Baskin on the alignment problem and on eqn (6) and (10) were very illuminating. I also wish to thank M. Dantus, H. Levy, C. Sipes; T. Rose and M. Rosker for helping with some of the figures and calculations, and for stimulating discussions. I am grateful to Professor H. Metiu and Dr R. Heather for communicating their results of ref. (27) and for the discussion. [A.H.Z. was a] John Simon Guggenheim Fellow. Arthur Amos Noyes Laboratory of Chemical Physics, Contribution no. 7844.
