Dear all,
I am doinf a FCI calculation on the H3 system in an alpha dec osf4.0
workstation.
The optimization runs OK, but the frequency calculation
crashes at the first FCI step:
---------------------------------------------------------------------------------
 Run Hamiltonian processor DAVIDSON
 Symmetry:                   5
 Trial vector:                  0.00
 Result vector:                 0.00
 Maximum iterations:           35
 Convergence threshold:         0.0000100
 RHS vector:                    0.00
 Hamiltonian shift:             0.0000000
 Output threshold:              0.0500000

Does anyone have a suggestion?
