Short summary
A photochemical source of peroxycarboxylic nitric anhydrides (PANs) in which a dialkyl ketone (acetone, diethyl-, di-isopropyl, or di-n-propyl ketone) in the presence of oxygen and nitric oxide is photodissociated by arrays of ultraviolet light-emitting diodes (UV-LEDs) is described. The source output was analyzed by gas chromatography and thermal dissociation cavity ring-down spectroscopy and modeled using the Master Chemical Mechanism.
