Van der Waals surface
Van der Waals surface area (abbreviated variously as vdWSA, VSA, WSA), also van der Waals surface or van der Waals envelope (after Johannes Diderik van der Waals) is the imaginary surface of the union of spherical atom surfaces defined by the so-called van der Waals radius of each atom in the molecule representation. The van der Waals surface enclosed volume reference is molecular volume.
CPK models of molecules may actually picture the van der Waals surfaces, if based on van der Waals radii.
