Electron Spin Resonance in a Gamma-Irradiated Single Crystal of Mercaptosuccinic Acid
Journal Article
·
· Journal of Chemical Physics
The four most intense resonances in the ESR spectrum of a gamma - irradiated single crystal of mercaptosuccinic acid are shown to be due to the same free radical which has four different orientations in the crystal. By analysis of the anisotropy in the spectroscopic splitting factor the principal values of the g tensor were found to be 2.003, 2.026. and 2.054. It is believed that the free radical HOOC -- CH/sub 2/--HCS-- COOH is responsible for the observed resonance. The model of Kurita and Gordy in which the electron spin density is concentrated in a nonbonding orbital of the sulfur atom successfully accounts for the features of the anisotropy of the g tensor.
