Quantitative Structure-Property Relationships for the Polarizability, Solvatochromic Parameters and Lipophilicity

The polarizability α vol , the solvatochromic parameters π * and β and the lipophilicity as expressed by log K ow are subjected to regression analyses using calculated molecular parameters within the MNDO scheme. The resulting linear one- and more-variable regression equations enable rapid approximate calculations for α vol , π * and β and log K ow of untested compounds; in particular, α vol is split into a molecular size and an electronic part which offers new possibilities for applications in quantitative structure-activity relationships
