Nitrogen-14 Nuclear Quadrupole Resonance Studies of Pyrimidine and Purine Derivatives
… classical and quantum mechanical descriptions of nuclear quadrupole resonance (nqr) are reviewed. Fundamental principles of nuclear spin thermodynamics are introduced to explain double resonance via level crossing (drlc), the experimental technique employed to detect ('14)N nqr resonances.

Frequency dependence on the temperature in nuclear quadrupole resonance of sodium bromate
The pure quadrupole resonant frequency dependence on temperature of the Br<sup>79</sup> isotope was examined from 4.2°K to 346°K. These data were fitted with the Bayer theory as extended by Kushida. The inequality of the two assumed modes of bromate-group vibration as well as the possibility of …

A study of the nuclear quadrupole resonance spectrum of beryllium in chrysoberyl
The interpretation of the data is done by two different methods. In method one each of the curves in Figure X is grouped separately with the curves of Figures VIII and IX to determine the matrix elements of the field gradient tensors, 1 since there are two different sites.
