Photoreactions of peptides Ala-Gly-Gly and Gly-Gly-Gly-Gly in the presence of potassium ferricyanide at 77 K were studied by modeling of ESR spectra. There were obtained parameters of ESR spectra of primary radicals of the peptide glycine residue appearing after decarboxylation, and of the secondary acyl radicals. Dependence of the second integrals of the experimental and triplet and singlet ESR spectra on irradiation time within wave lengths 410-510, 330-390 and greater than 530 nm was measured and discussed.
通过电子自旋共振（ESR）光谱建模研究了在77K下，丙氨酸 - 甘氨酸 - 甘氨酸和甘氨酸 - 甘氨酸 - 甘氨酸 - 甘氨酸肽在铁氰化钾存在下的光反应。获得了脱羧后出现的肽甘氨酸残基的初级自由基以及次级酰基自由基的ESR光谱参数。测量并讨论了实验的三重态和单重态ESR光谱的第二积分在410 - 510、330 - 390和大于530nm波长范围内对辐照时间的依赖性。
