I use Density Functional Theory to study the weak molecular interactions. I am using Gaussian09W program for simulating the molecular complexes. Can you please provide me information regarding the identification of dispersion interactions in optimized molecular complexes? Moreover please help me by providing the input methods or keywords in Gaussian programme which is required for studying the dispersion interactions. Because one of my papers got rejected recently, in which i had employed B3LYP methods . The reviewer commented me that B3LYP method is not appropriate to study the dispersion interactions. So Kindly help me on how to study the dispersion interactions in molecular complexes using Gaussian programme. Regards, N. K.
