英文摘要	We report on an experimental study of the vacuum ultraviolet photodissociation dynamics of nitrous oxide as a function of photolysis wavelength. In this study, both the N(D-2(J)) + NO (X-2 Pi) and N(P-2(J)) + NO(X-2 Pi) product channels were investigated using the time-sliced velocity ion imaging technique. Images of the N(D-2(J=5/2,3/2)) and N(P-2(J=3/2,1/2)) products were measured at seven and ten, respectively, photolysis wavelengths between 124.44 and 133.20 nm. The vibrational states of the NO products were partially resolved in the acquired raw ion images. The total kinetic energy release and the branching ratios of different vibrational states of NO products were determined. The vibrational state distributions of NO were found to be inverted for the N(D-2(J=5/2,3/2)) and N(P-2(J=3/2,1/2)) product channels. This phenomenon indicates that the N-O bond is highly vibrational excited during the breaking of the N N bond. Vibrational state resolved anisotropic parameters beta in both the N(D-2(J)) and the N(P-2(J)) channels were acquired. The small beta values (around 0.5) in the dissociation process suggest that transition states in a bent configuration play an important role in the formation of N + NO products.
