Abstract
A prescription for applying the method of molecular similarity calculations based on electrostatic potentials and fields is developed by consideration of a typical structureβactivity series. Firm conclusions are drawn about the nature of the grid of points surrounding the molecules and about the choice of geometry, but options for point charges are less clearcut.

The molecular surfaces of dierent sandalwood odour molecules have been investigated and compared with a group of structurally related substances without this odour impression to get more information about osmophoric regions. This has been done with the help of a new algorithm in a surface comparison
A set of procedures for rapid calculation of quantum molecular similarities from a& initio wave functions is discussed. In all cases a density fitting is carried out to eliminate the need of calculating costly four-centered integrals. It is proved that this methodology can be applied to large system
