Abstract
A new method is presented for the calculation of partition coefficients of solutes in water lipid systems. Log P values are calculated based on the charge densities of the atoms as determined by quantum mechanical methods. In this article, the results have been obtained from charge densities calculated by two methods: MINDO/3 and HΓΌckelβtype calculation based primarily on topology. Results are favorably compared with those obtained by fragment analysis.

## Abstract We present a detailed study of harmonic vibrational frequencies obtained with the selfβconsistent charge density functional tightβbinding (SCCβDFTB) method. Our testing set comprises 66 molecules and 1304 distinct vibrational modes. Harmonic vibrational frequencies are computed using an
