Abstract
Single crystals of the dipotassium salt of gluocose-1-phosphate were grown out of water or deuterium oxide and x-irradiated at 4.2 °K. The products of irradiation were identified by means of ESR and ENDOR spectroscopy. In crystals grown out of water, three different alkoxy radicals were observed as oxidation products. In partially deuterated crystals only one of the aforementioned alkoxy radicals was produced. A hydroxyalkyl radical, RHĊOH was also produced by loss of hydrogen from the C6′ position. Electrons trapped at intermolecular sites were identified. The distances between the electron and the protons of the polar hydroxy groups forming the trap were deduced from ENDOR measurements and found to be relatively large, namely 1.732 and 1.738 Å.
