✦ Synopsis

The dissociation energy of highly excited dimers is averaged over the regions of strictly bound, metastable and free states in the phase space. It is demonstrated that a substantial decrease of the effective dissociation energy can be expected for weakly bound dimers and conventional diatomics held respectively at normal or extremely high temperatures. Estimates are given for the two-temperature scheme. The role played by the formation of metastable dimeric states is discussed.

Spectroscopic parameters in an ensemble of the weakly bound dimers are derived making use of the quantum and classical statistical average over thermally excited rovibrational states. Argon dimers and oxygen dimers are taken as examples. It is shown that thermally averaged characteristics of dimers

Charge-transfer reactions of Ar+ with CH,Cl,\_, (n= l-3) at thermal energy have been studied by using a flowing-afterglow apparatus coupled with a low pressure chamber. Dissociative charge-transfer leading to CH: (91 k 5%) CH&l+ (95 k 2%), and Ccl+ (69 f 3%) are major product channels for CH,Cl, CH#
