| 摘 要： | 本文从(R)-(-)-1,3-丁二醇 ((R)-(-)-1,3-Butanediol) 的拉曼峰强和拉曼旋光峰强, 求得其键极化率和微分键极化率, 得出在拉曼过程中, 电荷主要沿H16 (或H15) O6C3C2C1O5所形成的 (六边) 环向外围的OH键和CH 键流动. 而此环内外化学键的微分键极化率的符号正好相反, 此意味着这个分子具有相当好的手性不对称性质.

| Abstract: | The Raman optical activity (ROA) of (R)-(-)-1,3-butanediol was described through the analysis of bond polarizability and differential bond polarizability, which were elucidated by Raman and ROA spectral intensities, respectively. Analysis shows that during the Raman process, the charge flows from the (six) rings formed by H16 (or H15) O6C3C2C1O5 to the peripheral OH and CH bonds. The analysis also shows that the signs of differential bond polarizabilities associated with the rings inside and outside are opposite. This means that the chiral asymmetry of this molecule is fairly distinct.
