The technique of electron-nuclear double resonance (ENDOR) is applied to the study of the hyperfine interactions in one (A) of the two radicals formed by x-irradiating single crystals of glutaric acid. It is shown that the other radical (B) can be destroyed with u.v. irradiation. Complete hyperfine tensors based on the EMR data are calculated for the A radical using an iterative procedure which is also prescribed. Comparing this data with the ENDOR measurements reveals an appreciable orientations disorder of the radicals as well as temperature dependent splitting. Small hyperfine interactions not resolvable in EMR spectra are observable via ENDOR. The experimental development is described in some detail.
A low temperature EMR system which permits in situ u.v. irradiation is described. The TE(011) microwave cavity, which operates at room temperature, accommodates the helium cold finger along the cavities' axis of symmetry.
