Many of the most common molecular simulation methods, ลฝ . ลฝ . including Monte Carlo MC and molecular or stochastic dynamics MD or SD , have significant difficulties in sampling the space of molecular potential energy surfaces characterized by multiple conformational minima and significant energy bar
## Abstract Absolute free energies of hydration have been computed for 13 diverse organic molecules using partial charges derived from __ab initio__ 6โ31G\* wave functions. Both Mulliken charges and charges fit to the electrostatic potential surface (EPS) were considered in conjunction with OPLS Le
