A photochemical method for producing proton nuclear polarization in phenolic biogenic molecules such as tyrosyl polypeptides and phenolic amines is described. The nuclear polarization is due to the reversible hydrogen-atom transfer from the phenolic hydroxy group to triplet photoexcited xanthene-dye molecules. Typical results obtained with insulin, catecholamines and other phenolic molecules are treated in detail.
描述了一种在诸如酪氨酰多肽和酚胺等酚类生物分子中产生质子核极化的光化学方法。核极化是由于酚羟基与三重态光激发的呫吨染料分子之间的可逆氢原子转移所致。详细讨论了用胰岛素、儿茶酚胺和其他酚类分子获得的典型结果。
