基于Abe对吸收和荧光光谱的溶剂频移的改进表达式（Bull. Chem. Soc. Jpn.，54，327（1981）; 58，3415（1985）; 61，3797（1988））。应用该方法对N，N-二甲基苯胺和苯胺分别得到39.5度和40.0度的角度，激发态的偶极矩都小于相应的基态的偶极矩。
A method for estimating the angle between the ground- and excited-state dipole moments is presented on the basis of Abe's improved expressions for the solvent frequency shifts of absorption and fluorescence spectra (Bull. Chem. Soc. Jpn., 54, 327 (1981); 58, 3415 (1985); 61, 3797 (1988)). Applications of the method to N,N-dimethylaniline and aniline give angles of 39.5-degrees and 40.0-degrees, respectively; the excited-state dipole moments are both smaller than the corresponding ground-state dipole moments.
