Abstract

RESP atomic charges for N-Acetyl-L-alanine-N'-methylamide (conformations C5, C7ax and C7eq) based on the Connolly surface algorithm and the HF/6-31G* theory level. Charges suitable for MD simulations using the Cornell et al. AMBER force field (and/or its adaptations). Charges derived using 3 mol. conformations and 10 mol. orientations (Rigid-Body Reorientation Algorithm) for each conformation. Charge values to be compared with those reported in the projects W-59, W-60 and W-61.
