Popis: The relationships between octanol/water partition coefficients (log P) estimated by reversed-phase high-performance liquid chromatography (RP-HPLC) and various bulk and electronic properties, calculated by molecular and quantum mechanics methods, of diphenyl ether (DPE) and phenopylate herbicides were examined. The three molecular parameters, van der Waals volume, dipole moment, and energy of the highest occupied molecular orbital, together accounted for 78-83% of the variation in the log P data. On the average, the predicted values using regression equations deviated from the observed values by only 0.13 and 0.19 log unit in DPE and phenopylate classes, respectively (.)
