Abstract

The vibrational and rotational product-state distributions of ND₂(Ã²A₁) has been probed following the photodissociation of ND₃ at 193.3 nm by time-resolved Fourier Transform infrared emission spectroscopy. The dynamics of the bond cleavage are inferred from the product state distributions by comparison with an earlier study of the photodissociation of NH₃. The degree of excitation about the minor rotational b/c-axes of the product is attributed to the amount of zero-point energy of the parent molecule in the ν₄ H-N-H (D-N-D) scissors bending coordinate of the NH₃/ND₃(Ã) predissociative state. A bimodal ND₂(Ã²A₁) distribution is observed for rotation about the primary a-axis, analogous to the NH₂ fragment formed in the photodissociation of NH₃.
