James L. Kinsey

D. R. Bullard-Welch Foundation Professor of Science Emeritus

Dr. Kinsey's research has touched upon a variety of areas in chemical physics/physical chemistry, most of them involved with dynamics of simple chemical reactions or molecular collisions. His most recent research deals with the dynamics of decomposition of photoexcited molecules [1-9]. It has often been pointed out that the separation of the fragments produced in a photodissociation is essentially a "half collision" or "half reaction." The Kinsey group's work on photoemission during photodissociation gives a spectroscopic means of following the motion of the transient state leading to photochemical fragmentation. This is accomplished by recording the spectrum of light emitted by the excited molecule. Because typical times for photodissociation (~10 psec) are much shorter than typical radiative life times (~10 nsec), there is only a very tiny (but finite) photon yield. The spectral characteristics of this radiation details of dynamic processes in the excited electronic state and in the ground electronic state as well. In the process of coming apart, the molecule sweeps through infinite displacements in molecular geometry, thereby developing the ability to radiate into extremely high vibrational levels of the electronic ground state. The pattern of intensities in these lines is a "footprint" of the dissociation process. Dr. Kinsey is no longer accepting new research students.
