Quasiclassical trajectory calculations have been performed for motion on anabinitiopotential energy surface to investigate energy transfer from N2(Athinsp;3sum;+u,v=1, 3 and 6) to H2and D2. Because of the unusual features of the surface, both vibrational relaxation and electronic quenching of N2(A) are observed, the latter process resulting in dissociation of the hydrogen molecule. It is deduced that coupling of thevibrationalmotions of the N2and H2molecules initiates the energy transfer process. The results are compared with experimental information on the quenching of N2(A) by sgr;hyphen;bonded molecules.
