Coherence Retention during Rotationally Inelastic Collisions of Selectively Excited Diatomic Sulfur,

摘要

There is ample experimental evidence for the presence of non-equilibrium population distributions, and the occurrence of non-Arrhenius reaction rate behavior, in a wide variety of combustion processes. A full understanding of such systems on a microscopic level requires that such effects be addressed. Recent experiments are now just beginning to provide information on the detailed quantum level dependence of inelastic and reactive collisions for a number of small molecules. However, the difficulty involved in carrying out such experiments means that theoretical computations of such rates will continue to be important for a number of systems. It is in turn crucial to have at hand experimental evidence concerning details of the collision dynamics which place constraints upon the theoretical formulations.
