Refractivity

The Refractivity Plugin is able to calculate molar refractivity. This descriptor is strongly related to the volume of the molecules and to London dispersive forces that play crucial part in drug-receptor interactions. Our calculation is based on the atomic method proposed by Viswanadhan et al.
