Abstract

Synopsis: Photodissociation of the pyridine molecules has been studied experimentally over the 16-70 eV photon energy range. Formation of the excited NH( A 3 Π) radicals has been observed among several other atomic and dia-tomic fragments, using the photon-induced fluorescence spectroscopy. Since the pyridine molecules do not con-tain the NH structural units, this is an indication of the bond rearrangement processes associated with migration of the hydrogen atoms prior to dissociation. The plausible mechanisms for the NH formation will be discussed.
