Abstract

RESP atomic charges for 10 solvent molecules (Dimethylsulfoxide, Ethanol, Trifluoroethanol, Methanol, Acetone, Acetic acid, Acetonitrile, Benzene, Toluene and Chloroform) fitted together based on the Connolly surface algorithm and the HF/6-31G* theory level using the R.E.D.-III program. Charges suitable for MD simulations using the Cornell et al. AMBER force field (and/or its different adaptations). Molecular orientation of the optimized structures controlled using the rigid-body reorientation algorithm implemented in R.E.D. (two or four mol. orientations for each structure).
Charge values identical (max. difference = +/- 0.0001, qtol = -5 in RESP) than those obtained in each project taken individually i. e. in the projects W-4, W-9, W-15, W-32, W-33, W-34, W-35, W-40, W-41 and W-42. Charge values to be compared with those reported in the projects W-47, W-48 and W-49.
