REACTIONS OF NITROGEN (II) OXIDE. A SPIN-FORBIDDEN TRANSITION OF NO OBSERVED IN SOLUTION SPECTRA

Abstract

The transition occurs at 3.5 ev in the UV spectra of NO dissolved in organic solvents. The observed vibrational frequencies range from 1/1100 cm in CCl4 to 1/1600 cm in CH3OH. These trends are correlated to the shift of electron density out of the Pi antibondin level upon formation of hydrogen bonds with the solvent. Investigations of the absorption spectrum of nitric oxide in polar solvents led to the discovery of a band with well resolved vibrational fine structure commencing at 3850A and extending to shorter wavelengths. This band is not observed in the gaseous spectra. The band was analyzed by assuming that it is due to a spinforbidden transition at about 4.5 ev above the ground state. (Author)
