[molpro-user] Question about MRCI

[molpro_user]

Dear colleagues：


    I am a new user of Molpro. I am having troubling about CI calculation of degenerate state. The energy of degenerate state can be accurate 8 digits after the decimal point but only 4 or 5 digits after the decimal point. For using Cs symmetry on polyatomic, I wonder the above phenomenon is normal or not. If not, is there any suggestion to improve the above problem?


Best regard
