A test of the Kassel quantum expressions for unimolecular rate constants and densities of vibrational states is described. Rate constants are calculated for nine reactions previously used in such tests, over a wide range of temperatures and pressures. The Kassel expression using the geometric mean o

โฆ Synopsis
The solution of the master equation for a thermal ununolecular reaction in the strong or effectwe-strong colltsion limit ls shown to weld a much srmpler expressron for the unimolecular rate constant than one denved prewously.

A semiclassical analysis of quantum-mechanical resonance lifetimes provides a framework for describing unimolecular dissociation rates near or below the adiabatic thresholds associated with saddles on potential energy surfaces. A formula which can be used when only one channel is effectively open is
## Abstract A new formulation of the Lindemann mechanism of unimolecular reactions in gaseous phase is presented, without the use of steady state hypothesis. It is hereby shown that the nature of applicability of steady state hypothesis in the regime of high reactant gas pressure is different from
