Quadrupole relaxation in nitrogen nuclear resonances

Abstract

The ¹⁴N resonance line-widths have been measured for a wide range of nitrogen compounds. The variation of line-width with viscosity of MeCn, EtCN, PrCN and Me₂NCHO in various solvents is discussed in terms of the theories of molecular correlation times. The values of the line-widths in substituted nitrobenzenes are discussed in terms of the quadrupole coupling constants. The relative line-widths in the azide ion are discussed in terms of its electronic structure.
