- 論文の詳細を見る
We report here special features of plasma-induced free radicals of monocarbohydrates such as α- and β-glucose on its comparison with those of amylose and cellulose. The simulated spectra disclosed that the observed spectra of α-glucose consist of four kinds of spectral components, two isotropic spectra [doublet (I) and (II)], assigned to a hydroxylalkyl radicals and an anisotropic spectrum [anisotropic doublet (a-D) (III)], assigned to an acylalkyl radical, and a large amount of dangling-bond site (DBS) (V) with an intermediate level of conversion which includes a mixture of ring-opened and/or conjugated structure of no structural significance. On the other hand, those of β-glucose consist of four kinds of spectral components, I, III, V and an anisotropic doublet of doublets (a-DD) spectrum (IV) assignable to the acylalkyl radicals.
