 Hi friends
 I am working on biomolecule intraction. I have optimized the structure of two my
 compound in both vacuum as well as solvent(PCM and cpcm model) using
 b3lyp/6-311++G** basis.for cpcm model I using syntax
 # b3lyp/6-311++g** opt freq scrf=(cpcm,solvent=H2O)
 I have several questions about using from Gaussian:
 1. I am asking weather this order is correct or not?
 2. can I use a solvent except solvents in gaussian09?
 3. How I can study biomolecule intraction in natural condition?
 4. How I study exchange structural?
 please help me
