The equilibrium geometries and fundamental frequencies of Na S are calculated at HF, 2 Ε½ . Ε½ . Ε½ . MP2 FC, FU , and MP3 with the 6-31G d basis set and at HF and MP2 FC, FU with the Ε½ . Ε½ . Ε½ . 6-31G d basis set, respectively. The total energy at MP2 FU r6-31G d -optimized Ε½ . Ε½ . Ε½ . geometry is com

The geometry of a proposed intermediate (a-dialkylamino nitrite ester) of N-nitrosamine synthesis from nitrites is studied by ab initio SCF methods. The energy of a zwitterion is calculated and found to be high.
## Abstract There are two values, β26.0 and β27.7 kcalβmol^β1^, that are routinely reported in literature evaluations for the standard enthalpy of formation, Ξ~f~__H__Β°~298~, of formaldehyde (CH~2~ο£ΎO), where error limits are less than the difference in values. In this study, we summarize the report
Ab initio molecular orbital theory has been used to study the mechanism of the formation of C,H, ' from the reaction of CH,+ with acetylene. The highest level geometry optimizations and frequencies were computed at MP2-FC/6-31G\* \* ; single point energies of all the critical structures were compute
