ABSTRACT
Reports on the ultrafast excitation of an oxygen-hydrogen stretching vibrational followed by photodissociation of the energized molecules that allows direct observation of the time for intramolecular energy redistribution in isolated nitric acid. Increase in the photodissociation yields as a function of time.

    We report an imaging study of nitric acid (HNO3) photodissociation near 204 nm with detection of O(1D), one of the major decomposition products in this region. The images show structure reflecting the vibrational distribution of the HONO coproduct and significant angular anisotropy that varies...
