A combination of zero field triplet state techniques are used to study the excited electronic states of a series of flavin and flavin related molecules both in single crystals and glass matrices. Particular attention is given to the effects of solvent interaction on the triplet state properties of the flavin molecules. The total phosphorescence decay rate constants at 1.4 degrees K are reported for the flavin molecules in polar and nonpolar solvents. The rate constants are then correlated to the degree of solvent interaction. Results indicate possible complex formation between the isoalloxazine and adenine groups in FAD. Finally, the results and possible interpretation on the study of a flavoenzyme, L-amino acid oxidase are presented.
采用零场三重态技术的组合来研究一系列黄素及黄素相关分子在单晶和玻璃基质中的激发电子态。特别关注溶剂相互作用对黄素分子三重态性质的影响。报道了黄素分子在极性和非极性溶剂中1.4 K时的总磷光衰减速率常数。然后将速率常数与溶剂相互作用程度相关联。结果表明黄素腺嘌呤二核苷酸（FAD）中的异咯嗪和腺嘌呤基团之间可能形成复合物。最后，给出了对黄素酶L-氨基酸氧化酶研究的结果及可能的解释。
