研究了在不同溶剂中测定和在不同波长时激发的香豆素酮类化合物的荧光光谱, 结果明显地指出, 在溶液中呈现出由位阻旋转引起的许多不同的旋光异构体.

关键词: 呋喃 P, 香豆素 P, 苯酰基, 异构体, 空间效应, 噻吩 P, 磷光分析, 光学异构

The phosphorescence spectra of acylcoumarins I (R = Ph, 2-furyl, 2-thienyl) excited at different wavelengths or measured in different solvents have been investigated. Several rotamers caused by hindered rotation were present in the solns.

Key words: FURAN P, COUMARIN P, BENZOYL GROUP, ISOMER, STERIC EFFECT, THIOPHENE P, PHOSPHOROMETRIC ANALYSIS, OPTICAL ISOMERISM
