Abstract
Mechanisms of the proton transfer in dimeric associates of formic acid with nitrous, nitric, orthophosphoric, and sulfuric acids were studie d by the ab initio (HF/6-31G*) method. The mechanism of the cooperati ve (concerted or one-step) proton transfer was shown to occur in all c ases. The calculated activation barriers of the proton transfer reacti ons for the associates investigated are equal to 19.9, 14.2, 13.3, and 10.7 kcal mol(-1), respectively.
