Summary:This study examines the 248-nm photodissociation of nitric acid (HNO 3) and characterizes the translational energy distribution of the nascent photofragments. Photofragment translational spectroscopy with VUV photoionization detection evidenced one product channel, cleavage of HNO 3 to form OH + NO 2, and established an upper limit on the contribution from the O + HONO formation channel of 3%. These data contribute an independent measurement to a literature debate regarding the branching between these two channels.
