    • Abstract

       

      The Raman spectra of pyridine N-oxide and its solutions in phenol, methanol and dioxan have been recorded. The band at 1254±10 cm.−1 has been assigned to the N-O stretching vibration. The variations in the double bond frequencies of pyridine ring, and in the frequency of N-O bond, owing to hydrogen bond formation, have been listed. On conversion of pyridine to pyridine N-oxide the various frequencies attributed to the different modes of vibrations in the pyridine ring get altered as a result of the considerable disturbance caused by the new bond.
