Excited state ACPF

[Shai Ronen]

 Hello,

 I'm interested in doing ACPF calculations for multiple states, that is,
ACPF for a few roots following SA-MCSCF. This is quite general so the
details are not important (I think). I had some problems with this before.
Sometimes it didn't converge (MRCI did), and I got a communication from
H.-J. Werner that it is not possible to do that.
However more recently, for my calculations of interest, although I encounter
some converegence warning about the higher roots during intermediate
iterations, the final energies seem to converege normally and the program
exits normally.  My question is, in view of the above, are such results
trustable?


 Many thanks in advance,
 Shai Ronen
