Kashiwagi, Michio published the artcile< Electron spin resonance of irradiated single crystals of alloxan monohydrate>, Related Products of 2244-11-3, the main research area is ALLOXAN IRRADIATED ESR; ESR IRRADIATED ALLOXAN.
X-ray irradiated single crystals of alloxan monohydrate were subjected to E.S.R. studies. Irradiation gives rise to radicals I by the abstraction of a hydroxyl group. The principal values of g-factors of the radicals are g1 = 2.0021, g2 = 2.0042, and g3 = 2.0060. The principal values of coupling constants with hydroxyl H are A1 = 3.1, A2 = -5.9, and A3 = -7.4 gauss. Spin ds. on the C and H atoms of •C-OH were evaluated from the 13C coupling constant Under the assumption of a planar structure for •C-OH and from consideration of the electronic structure of the radical, the directions of the principal values were concluded as follows. The directions of g1 and A2 are perpendicular to the radical plane, while that of g3 bisects the exterior angle of •COH. The direction of A1 is parallel to the OH bond.
