摘要：

The X;∑;,A’;△;,A;∑;,1;Π;,and B;∑;electronic states of oxygen molecule（O;） are calculated by the multiconfiguration self-consisted filed（MRCI）+Q method with the scalar relativistic correction and core-valence correlation correction.The obtained spectroscopic constants of the low-lying bound states are in excellent agreement with measurements.Based on the accurately calculated structure parameters,the opacities of the oxygen molecule at the temperatures of 1000 K,2000 K,2500 K,and 5000 K under a pressure of 100 atm（1 atm=1.01325×10;Pa） and the partition functions between 10 K and 104 K are obtained.It is found that with the increase of temperature,the opacities for transitions in a long wavelength range are enlarged because of the larger population on excited electronic states at the higher temperatures.
