DIRECT MAPPING OF VIBRATIONAL-SPECIFIC ANGULAR-DISTRIBUTIONS OF THE POLYATOMIC REACTION-PRODUCT - CN-2-]DCN+D(D)

A newly developed Doppler-selected time-of-flight (a 3D) method was ap plied to map out for the first time the vibrational-specific angular d istributions of the DCN product from the title reaction. A tentative v ibrational assignment was given for the observed structures. It was fo und that the nascent DCN is formed with substantial excitations in bot h C-D stretch and DCN bend modes. While the pure C-D stretch and those associated with low bend excitations are predominantly backward scatt ered, the highly excited DCN in both modes also exhibit a substantial forward scattered component in the angular distribution.
