✦ Synopsis


The polarization (energy lowering, electronic displacements and induced dipoles) and cbargr-transfer effects are separately computed for the approach of a proton in various directions towards formamide, and the further effect of the geometrical deformations of the attacked molecule is established. None of these effects appexs upable to reverse the prediction made on the basis of electrostatic potentials pointing to the oxygen atom as ths primary protonation site.

Ab initio CAS SCF/MRSDCI calculationswere performed for the naked CuCHz cluster. The ground state is predicted to be the 'B, state having a planar structure. The state arises from Cu('S) and CH2(iB,). The Cu-CH, o bond has a covalent character and the binding energy is 2.23 eV (5 I kcal/mol). The op
