The double proton transfer process has been studied for the oxalic acid dimer in the gaseous state and for crystalline form at the non-empirical level. The correlation energy corrections have been taken into account at the MP2 level as well as crystal field effects were considered. The results of our calculations enable a reasonable interpretation of low potential barriers, observed in NMR experimental studies of some molecular crystals involving carboxylic dimers. The possible mechanisms of the double proton transfer are considered.
