在220~540 nm范围内测量了具有新光谱性质的8-氨基-8-去甲基-D-核黄素的吸收光谱、CD光谱和MCD光谱，并用高斯波数曲线(从I带到X带)进行了分析。对Pariser-Parr-Pople哈密顿量进行了半经验计算，研究了新的光谱性质和5位上的反应活性。理论计算结果和实验结果表明，新的光谱性质是8位氨基取代的结果。
The absorption, CD and MCD spectra of 8-amino-8-demethyl-D-riboflavin, which showed novel spectral properties, were measured in the spectral region from 220 nm to 540 nm and the spectra obtained were analyzed in terms of Gaussian wave number curves (from band I to band X). Semi-empirical calculations of the Pariser-Parr-Pople Hamiltonian were performed to investigate the novel spectral properties and the reactivity at the 5-position. The theoretical results as well as the experimental results showed that the novel spectral properties were a result of amino substitution at the 8-position.
