摘要
本文报导了丙酮在10种不同溶剂中的红外光谱,并从溶剂的折射率(n)、介电常数(ε)和溶剂的极性参数〔E_T(30)〕等三个方面研究了丙酮红外光谱的溶剂效应。用回归分析及单参数和双参数方程处理数据,得到了几个较好线性相关的回归方程。
The infrared spectra of acetone in ten solvents are determined. The solvent effect on the infrared spectra of acetone in 10 solvents is studied. The results show that the shift of spectra are function of f(ε), f(n.ε) and ET(30) value of solvents respectively. Here e is the dielectric constant, n is the refractional index of the solvent used and f (ε) = (ε-1)/(2ε + 1), f(n. ε) = (n2 -1)/(2n2 + 1) + (ε-1)/(2ε +1). By treating the data with monoregression and dual regression analysis, the better linear correlation is obtained.
