✦ Synopsis

The approximations developed to determine the enerky distribution function of molecules activated above energy decomposition threshold. from experimental data. have been tested. The approach involved the theoretical (RRKMI calculations of "pseudoexperimental" data for a variety of activated energy distributions. (Single or double Gaussian representations were used in all cases. 1 Subsequently the algorithms mentioned were applied in order to recuperate the original ti.e., input) energy distributions from these pseudoexperimental data. The results obtained provide strong evidence in favor of the validity of the algorithms and illustrate the necessary requirements for their applications. . A trend toward lower accuracy as the energy distributions move to higher energies has been observed. Evidence of the influence of the distribution width is also reported. The origins of the approximation errors have been studied, and ways for further improvement are suggested.
