Dear Netters: I am in need of data on N-O bond lengths for calibrating some semi-emperical calculations. Experimental bond lengths would be good, but I will take high quality ab initio ones too. Does anyone know of sytematic studies? I prefer saturated systems, like H2NOH, in a variety of conformational and charge situations. Thanxs sincerely for any help you can give, K.R.Fountain/sc18 at.at NEMOMUS
