英文摘要two potential energy curves for the ground electronic state x(2)pi and the first excited electronic state a(2)sigma(+) of oh radical have been calculated using the internally contracted multiconfiguration-reference configuration interaction (ic-mrci) method including davidson correction. and they were fitted to analytical potential energy functions using the muffell-sorbie potential function to deduce the spectroscopic parameters: equilibrium bond length r(e), rotation coupling constant omega(e), anharmonic constant omega(e)chi(e), equilibrium rotation constant b(e) and vibration-rotation coupling constant alpha(e). these constants and higher-order anharmonic constant omega(e)y(e), were also calculated by polfit. most of the values obtained are in excellent agreement with experimental results. the calculated dissociation energy d(0) for oh(x(2)pi) is 35568.86 cm(-1), which is in excellent agreement with the recent experimental value (35565+/-30) cm(-1). the calculated dissociation energy d(0) for oh(a(2)sigma(+)) is 18953.93 cm(-1). the calculated vertically excited energy from the ground state x(2)pi (v = 0) to the first excited state a(2)sigma(+) (v = 0) is 32496.42 cm(-1).
