Control of a chemical reaction far from the Franck-Condon point by single-pulse resonant and non-resonant light-matter interaction.

Dietzek, Benjamin LU ; Brüggemann, Ben LU ; Pascher, Torbjörn LU and Yartsev, Arkady LU orcid (2007) In Journal of the American Chemical Society 129(43). p.13014-13021
Abstract
Using optimal control as a spectroscopic tool we decipher the details of the molecular dynamics of the essential multidimensional excited-state photoisomerization - a fundamental chemical reaction of key importance in biology. Two distinct nuclear motions are identified in addition to the overall bond-twisting motion: Initially, the reaction is dominated by motion perpendicular to the torsion coordinate. At later times, a second optically active vibration drives the system along the reaction path to the bottom of the excited-state potential. The time scales of the wavepacket motion on a different part of the excited-state potential are detailed by pump-shaped dump optimal control. This technique offers new means to control a chemical...
