Combining the above treatments with the theory of electronic spectra we have derived the general equations for describing the mutual relation between oxidation-reduction potentials and electronic spectra. These kinds of equations have led to the other formulas, by which we have first succeeded in describing the substituent effect on electronic spectra by means of substituent constants. The equations mentioned above were carefully checked by various kinds of experiments. Secondly we have extended our work to the basic study of QSAR. New methods were presented for evaluating partition coefficient and pK_a simultaneously. To reduce the chance correlation among descriptors in the multiple regression analysis (MRA) the usefulness of the combination of principal component analysis and MRA was verified. Also, we have discussed new descriptors scaled for steric effect and drug-receptor interaction on the ground of molecular electronic states. Finally we have reported the new flow type in situ electrolysis cell for recording ESR and cyclic voltammograms of unstable free radicals at various temperature. ESR spectra thus obtained were applied for interpreting the molecular conformations and molecular interactions of free radicals.}, pages = {1--21}, title = {<総説>薬物関連化合物の分子物性についての研究}, volume = {38}, year = {1989} }
