Abstract
The radiolysis mechanism of oligosaccharides has been extensively studied during the last years with the Electron Spin Resonance (ESR) technique [1–4]. We report here experiments carried out using the spin trapping method [5,6] on c-D-glucopyranose, β-D-glucopyranose, 1-O-CH3-α-D-glucopyranose, sucrose and oligosaccharides Gn (defined as O-α-D-glucopyranosyl-(1->4)n-1-α-D-glucopyranose) with n-2 to n-7, and several 13C labeled derivatives of these compounds. The gamma induced radicals S• are converted into long-lived nitroxide spin adducts in the liquid phase (water-ethanol [2:1]) by reaction with 2-methyl-2-nitrosopropane (MNP or tBu-N-O):
