- ItemOpen AccessLigand isotope vibrational studies of metal(II) complexes with particular reference to heterocyclic N-oxides(1987) Watkins, Gareth Mostyn; Thornton, David AA critical examination of the characteristic N-O vibrational frequencies of aromatic N-oxides questions the widely held assignment of αN-O (840cm⁻¹) and YN-O (47oon- 1). The present investigation supports the assignments of αN-O (470cm⁻¹) and γN-O (280cm⁻¹), with the assignment of the band at 840cm⁻¹ as being vring coupled with νN-O.
