Dear CCL-lister,
    I am now using Gaussian98 to do CASSCF calculation,but now
 I have some problem. I want to use a state-average CAS orbital
 to optimize the upper state geometry of the two state that
 are close in energy. How to realize this kind of calculation in G98?
 Does anyone has experience on this and gives some advice?
    Thank you.
