Conformations of Pyrrolidinium Ion Studied by Molecular Orbital Calculations
نویسنده
چکیده
Ab initio HF/6-3 lG(d. p) and density functional theory B3LYP/6-31G (d, p) calculations were carried out to investigate the conformations of pyrrolidinium ion. Two conformations, corresponding to twisted (C2) and envelope (Cs) forms were optimized. Vibrational analysis showed that the twisted form is at a local minimum point and the envelope form at a saddle point. The energy difference between the conformations is ca. 2 kJ m o r 1 .

Structural and magnetic properties of purine and pyrimidine nucleotides (CMP, UMP, dTMP, AMP, GMP, IMP) were studied at different levels of ab initio molecular orbital theory. These calculations were performed at the hartree-fock level and density functional B3LYP methods. Geometries were fully optimized by following Cs symmetry restrictions. The standard 6-31G** basis set which includes polari...
