The structure and dissociation energy of the ground state of OH and SH are calculated using QCISDT/6-311++G3df,2pd method and QCISDT/ 6-311++G3df,2pd. Based on the theory of atomic and molecular statics, the reasonable dissociation limit for the ground state X2Π of OH is derived. The potential energy curve and relevant optical constants of this state are obtained by least square fitting to the Murrell-Sorbie function. All calculation results are in good agreement with the experimental data.
