英文摘要Sliced velocity mapping ion imaging technique was employed to investigate the dynamics of the hydroxyl elimination channel in the photodissociation of nitric acid in the ultraviolet region. The OH product was detected by (2+1) resonance enhanced multiphoton ionization via the D(2)Sigma(-) electronic state. The total kinetic energy spectra of the OH+NO(2) channel from the photolysis of HONO(2) show that both NO(2)((X) over tilde (2) A(1)) and NO(2)((A) over tilde (2)B(2)) channels are present, suggesting that both 1(1)A '' and 2(1)A '' excited electronic states of HONO(2) are involved in the excitation. The parallel angular distributions suggest that the dissociation of the nitric add is it fast process in comparison with the rotational period of the HNO(3) molecule. The anisotropy parameter beta for the hydroxyl climination channel is found to be dependent on the OH product rotational state as well as the photolysis energy.
