Analytic first derivatives of the electronic energy are used to obtain the optimum orbital exponents for molecular SCF wavefunctions. We have employed the McMurchie-Davidson formula, since the energy derivatives require evaluation of molecular integrals with high angular momenta. Optimized orbital e
## Abstract The analytic energy gradients for the combined fragment molecular orbital and polarizable continuum model (FMO/PCM) method are derived and implemented. Applications of FMO/PCM geometry optimization to polyalanine show that the structures obtained with the FMO/PCM method are very close t
