Photodissociation dynamics of cyanamide at 212 nm

초록

Photodissociation dynamics of cyanamide (NH2CN) at 212 nm has been investigated by measuring rotationally resolved laser induced fluorescence spectra of CN fragments exclusively produced in the ground electronic state. From the spectra, rotational population distributions of CN as well as translational energy releases in the products were obtained. The measured average rotational energies of CN were 12.4 +/- 0.5 and 11.6 +/- 0.5 kJ/ mol for v '' = 0 and v '' = 1, respectively and the center of mass average translational energy release among products was 41.8 +/- 6.4 kJ/mol. The observed energy partitioning was well represented by statistical prior calculations, from which it was suggested that the dissociation takes place on the ground electronic surface after rapid internal conversion.
