A single crystal with a long hexagonal needle was obtained by slow cooling of a methanol solution containing n-C/sub 8/ and urea. Gamma irradiation was made with a /sup 60/Co source at 77/sup 0/K in the dark for 3 hr. The anisotropic ESR parameters of e/sup -//sub t/ obtained suggest that the ground state wave function of e/sup -//sub t/ in urea clothrates cannot be described by a spherically symmetrical s-type wave function only and that nuclei surrounding e/sup -//sub t/ are situated in an orderly manner according to the symmetry of the crystal. Possible e/sup -//sub t/ sites may be suggested to be a space between a guest molecule and a tubular wall composed by urea and/or a tubular void between guest molecules. Further experiments are needed for determination of the e/sup -//sub t/ sites. (LK)
