Dear CCL Members,
 I have a couple of questions about excited state calculations using
 MOPAC. I would like to do geometry optimization at the first excited
 state. I think EXCITED keyword  or C.I.=n ROOT=2 can be used for this.
 But they give different geometry with different energies. If I use CI,
 the first root is the correction for the ground state energy, and second
 one is for the first excited state state and so on. is that correct?
 I will be very greatful if somebody can give me informations in details
 about excited state optimization with MOPAC or some helpful references.
 thanks in advance
 Nuran
