Dear Molpro-user group,
I've been trying to do an excited state CI calculation on Xe_2_I ; I've been using a state averaged MCSCF calculation as the reference.
I've had no success, and I keep getting one of two errors, depending on how many states I try to converge to/avereage.
Below is a discription of what I know; If anything's unclear, please feel free to email me at [EMAIL PROTECTED]
I could use some help with why these errors are occuring.
Thanks,
Yann Tambouret

" This error was printed during a MULTI run.
This is the input file that produced the first error.
The second error was produced when some of the commented-out cards were included.
The memory alocated is so large because, becuase on some runs the jobs were killed (by our batch system) for running out of memory (used over 7 Gigs!)
