✦ Synopsis
Al1 quadratic, cubicand quartic force constantsassociated with the VF_H and VF_H.__O stretching of F-H---OH+ have been computed employing the confiiuratbn interaction approach. The contribution of quadrupole excitations was also estimated. The Y~__~, ZJ~H.. .Q modes and the deuterated analoguis have been reconstructed using ail the computed force constants.

The C=O bond length and fc=o,c=o, the corresponding harmonic stretching force constant, are calculated ab initio using the 4-31G basis set (augmented by polarization functions on the sulfur and chlorine) with full geometry optimization for the monosubstituted carbonyl compounds RCHO, where R = H, CH
## Abstract Kinetics for the reaction of OH radical with CH~2~O has been studied by single‐point calculations at the CCSD(T)/6‐311+G(3__df__, 2__p__) level based on the geometries optimized at the B3LYP/6‐311+G(3__df__, 2__p__) and CCSD/6‐311++G(__d__,__p__) levels. The rate constant for the reacti
Basis set expansion and correlation effects on computed hydrogen bond energies of the positive ion complexes AH, \* for AH, = NH3, OHz and FH, have been evaluated. The addition of diffuse functions on nonhydrogen atoms is the single most important enhancement of split-valence plus polarization basi
