Paramagnetic Resonance Absorption in Chromic Chloride

Abstract

The paramagnetic resonance absorption of powdered anhydrous chromic chloride has been re-examined at a frequency 9308 Mc/sec. The line width between points of maximum slope was found to be 79 gauss; the line width at half-height was 148 gauss; and the measured root-mean-square width was 103 gauss. The line width at half-height is considerably smaller than the width calculated for dipole-dipole broadening on the assumption of a Gaussian line shape. The effective $g$ value was found to be 1.997±0.003.
