Time Evolution of Unimolecular Processes in Isolated Molecules by Crossed Laser and Molecular Beams.
Abstract
The authors have developed a new technique, double absorption photofragment spectroscopy, in which a molecular beam is crossed with an initiation laser pulse followed, after a delay time, by a probe laser pulse and observe the recoiling photodissociation fragments with a mass spectrometer. This technique should allow the observation of the time development of unimolecular processes in isolated molecules over a time span from picoseconds to milliseconds. A first demonstration has been performed, the observation of the time evolution of predissociation in I2B state molecules as a function of their vibrational and rotational state distribution.
