Ab initio SCF calculations with the 6 -3 1 ~ basis set for the thymine dimer (cys-syn form) and the thymine dimer radical cation are reported. The fusion of the thymine bases at the C5 and C6 positions involves the formation of a cyclobutane ring with puckering. The puckering causes a notable differ

β¦ Synopsis
Ab initio calculations are performed for AgNH 3 and Ag+NH3 at the MP2 level of theory. The equilibrium structures show C3v symmetry, the Ag-NH 3 (Ag+-NH3) stabilization energy is 0.20 eV (2.00 eV). The frequencies of the silver-ammonia stretching and bending vibrations are calculated. The theoretical value of the adiabatic ionization potential (5.82 eV) is in good agreement with recent experimental data.

Structures of a-hydroxybenzylic cations and their conjugate bases, which cover a wide variation of stability, were optimized by means of ab initio molecular orbital method at the RHF/6-31G\* level. Total energies were calculated at the MP2/6-31G\*//RHF/6-31G\* ZPE (scaled 0.9) level. Calculated rela
The geometries and vibrational frequencies of MgO +, Mg2 O+, and Mg3 O+ were calculated using high level ab initio and density functional theories. Mg20 + (D~h, 2E~ ) is linear while the planar T-shaped (C2v, 2B2) and Y-shaped (C2v, 2Aj ) Mg30 + structures are essentially degenerate. MgO Γ·, Mg20 + a
