Structure of Nuclear Quadrupole Resonance Line I. Solid Iodine

Abstract

The complex structure of the line which was found in the nuclear quadrupole resonance in solid iodine was studied with recording instruments. The recorded pattern of the low-frequency line spreaded in the range of about 80 kc and resolved into five lines at least. The pattern changed considerably when the radiofrequency field was orientated with respect to the crystallographic axes. The structure was explained to be caused by the electron-coupled spin-spin interaction.
