1942 Jrnl. Amer. Chem. Soc. 64 2941/2 We suppose hydrogen-bonded structures to be chiefly contributing to a lower state and normal and quadrupolar structures to higher levels.

1959 G. Troup Masers ii. 28 This statement can be generalized, because the dipole moment may be electric or magnetic; or the moment may be of higher order, quadrupolar, for example.

1972 Science 26 May 903/3 The author directly proceeds to describe the effects due to quadrupolar and hyperfine interactions between electrons and nuclei.

2002 C. R. Yonker & M. M. Hoffmann in Ya-ping Sun Supercriti. Fluid Technol. ii. 72 The peak width at half height of the quadrupolar nuclei is directly related to the viscosity of the solution.
