Abstract:

Polyatomic molecules containing chains of identical valence groups are dissociated with high probabilities when sliding along crystallic surfaces. Recently, we developed a model of collective vibrational excitation and dissociation of such molecules. In the present article we use this model to elucidate the specific influence of chains formed by identical valence groups in polyatomic molecules on their dissocia- tion probability. In addition, a new experiment is presented providing evidence of this influence.
