This paper is a continuation of previous work on the CH 2O-NH 3 system. The supermolecule approach is applied by using a minimal type (MINI) basis at both the SCF and the correlated levels. The results have shown that only certain orbitals play a role in the counterpoise SCF energy ...
What is the Lewis dot structure for CH2O ? Lewis Structure: The first step towards writing the Lewis structure of a molecule is to arrange the constituent atoms according to the structure of the molecule. In case of simple covalent molecules, if only the molecular formula is known, then the...
