The ground state structures of 8-methylthioquinoline and its two derivatives were fully optimized at B3LYP/6-31+G level,and their absorption spectra were calculated using TD-DFT method.Calculation results agree with e...
The equilibrium geometrical optimizations and frequency calculation on B2N2 molecule in the singlet have been made at B3LYP/6-311+G*and CCSD/6-311+G*levels,respectively.The seven stable equilibrium structures were obt...
The Equilibrium geometrical optimizations on OCS linear and nonlinear molecules in the singlet and triplet states have been made using density functional theory B3LYP method with 6-31l++G**and aug-CC-pVTZ basis sets.T...
The alcoholization reaction mechanism and kinetics of benzothiadiazole were studied by HF and B3LYP method sat the level of 6-31G.The geometric structures of reactants,products,intermediates,and transition states in...
