empirical parameter

The frequencies of the carbonyl stretching vibrations in single solvent systems were correlated with empirical parameters of solvent polarity that include single empirical parameters and multiparameter .

对于一元溶剂效应的研究，主要是通过各样品的羰基伸缩振动频率和各种溶剂参数进行相关分析。

Three parameters, equalized molecular electronegtivily Xcq, polarizability effect index of alkyl PEI and the charge on the oxygen atom of the hydroxyl in the alcohol Σqo , were used to analyze the solvatochromic parameter ETN by using multiple regression.

利用分子的均衡电负性Xcq,烷基的极化效应指数PEI以及醇分子中羟基氧上的电荷∑qo三个参数,对一系列醇类溶剂的溶剂化显色参数ETN,运用多元线性回归的方法进行了相关分析,并与基于分子表面静电势参数的分析进行比较。
