Effects of deuterium substitution on the electron spin resonance of x- irradiated organic compounds were investigated. The compounds range from carboxylic acids, amino acids and amides to proteins. Substitution of deuterium for the hydrogens of polar groups--hydroxyl, carboxyl, and amino-- showed that the hydrogens of these groups generally do not contribute, or give only a slight contribution, to
研究了氘取代对 x 辐照有机化合物的电子自旋共振的影响。这些化合物的范围从羧酸、氨基酸和酰胺到蛋白质。用氘取代极性基团(羟基、羧基和氨基)的氢表明这些基团的氢通常对共振模式的超精细结构没有贡献,或仅贡献很小的贡献。然而,发现了例外,特别是甲酸和甘氨酸。大多数情况下,与碳键合的氢给出了 esr 图案的超精细结构。在某些情况下,由氘取代提供的附加信息允许对自由基进行相当明确的鉴定。(授权)
