SCF-MO calculations for the 1:2 hydrogen-bonded complex Me20..(HC112 predict a structure where both HCl molecules are bonded to the oxygen in a roughly tetrahedral arrangement. Agreement between calculated and observed energy changes is very satisfactory. Population analysis is used to investigate

โฆ Synopsis
The electronic structure of the three possible configurations HOO'...H20 hydrogen bonded systems, with full geometry optimization is studied using the semi-empirical UHF-INDO method.
In the models proposed, individual molecules undergo hindered rotation and oscillatory translational motion.
The linear model is predicted to be far more stable than the other structures. For this structure the calculated stabilisation energy and geometry follow the same trend as that found in the Hamilton and Naleway calculations [l]. Ionization potentials, net charges and spin redistribution are discussed in the terms of reactivity.

The hydrogen bonding of 1:1 complexes formed between formamide and methanol has been investigated using DFT and MP2 methods at varied basis set levels from 6-31g to 6-31++g(2d, 2p). Five reasonable geometries are considered with the global minimum being a cyclic double-hydrogen bonded structure. The
