Dear sir <br> I am trying to calculate excitation energies of low lying 10 states using EOM-CCSD method my molecule is open shell ,it's not giving EOM results of 10 states(I think it works only for open shell) please suggest me which is the better option to calculate a lot of excited states. Here i am attaching my input file.<br>
<br> Thanking you sir <br> S.Nagaprasad Reddy<br>
