【 摘 要 】

Photodissociation dynamics of cyanamide (NH₂CN) at 193 nm has been investigated by measuring rotationally resolved laser induced fluorescence spectra of CN fragments, from which rotational population distributions of CN as well as translational energy releases in the products were obtained. From quantum chemical molecular orbital calculations, a mixture of the n �? �?* and the transition to a state of the ionic character was found to be responsible for the absorption whereas the n �? �?* transition results in the absorption at 212 nm where the dynamics of dissociation was previously studied. The observed energy partitioning was well represented by statistical prior calculations, from which it was concluded that the dissociation takes place on the ground electronic surface after rapid internal conversion.
