A new method is presented for the calculation of partition coefficients of solutes in octanol/water. Our algorithm, XLOGP, is based on the summation of atomic contributions and includes correction factors for some intramolecular interactions. Using this method, we calculate the log P of 1831 organic compounds and analyze the derived parameters by multivariate regression to generate the final model. The correlation coefficient for fitting this training database is 0.968, and the standard
