Modifications are made to a previously developed scheme for calculating atomic charge which uses orbital electronegativity and which requires minimal calculational effort. The introduced changes are a result of deficiencies noted in the earlier method which were due to an inadequate accounting of ef

A simple electronegativity method is used to calculate atomic charges for molecules of interest to biochemistry. These include purines, pyrimidines, and amino acids. Results are compared to those obtained from other theoretical methods (ab initio and semiempirical) as well as to nuclear magnetic res
A previously developed method for calculating atomic charge in neutral molecules is modified so as to account for charged molecular species. The method is based on the orbital electronegativity (EN) concept and utilizes an EN equalization principal. Since only one linear equation is required per bon
Although the qualitative concept of partial charges of atoms in molecules is widely accepted and used among chemists, the assignment of quantitative values is met with difficulties. Experimental methods give only indirect access to atomic charges and different interpretations might result in varying
