An FWA calcubrion and a direct ium over slates is used to calculate second-order optical properries and van der Waalr coefficients. A basis set expansion fechnique is used and no conIinuu.m-:ike functions are included in the basis. However, unlike other methods we do not force the basis funclions 10
