harmonic frequencies and dissociation energies of the ground state of H2
HF were calculated using Quadratic CI method including single and double substitutions(QCISD).The potential curves were scanned using the QCISD /6-311++G(3df
3pd)method for the ground state.The potential energy function and relevant optical constants(ωe
ωexe
βe
αe)of this state were obtained by least square fitting to the Murrell-Sorbie function.All the calculating results in good agreement with experimental data.
