【Abstract】 With energy gradient complete optimization,PM3 in SCF-MO calculations have been performed to obtain four molecular geometry configurations of 1-ethylene-silacyclohexane-based liquid crystal compounds.Some molecular properties (heat of formation and dipole moment etc.) are also obtained.The calculated results are discussed in detail relating the classical organic electronic theory.更多还原
