Hello.
I want to calculate the excitation energies of the excited states using double hybrid density functional like B2PLYP.
However, when I used this rem section, the error message was occured.
$rem
JOBTYPE = SP
METHOD = b2plyp
BASIS = 6-31G*
CIS_N_ROOTS = 3
CIS_SINGLETS = TRUE
CIS_TRIPLETS = TRUE
UNRESTRICTED = FALSE
SYM_IGNORE = TRUE
SYMMETRY = FALSE
SCF_ALGORITHM = DIIS
MAX_SCF_CYCLES = 512
SCF_CONVERGENCE = 8
THRESH = 14
MEM_TOTAL = 24000
MEM_STATIC = 4000
$end
Q-Chem fatal error occurred in module libgen/rem_setup.C, line 1104:
TDDFT is not available for double hybrids!
So I think time-dependent double-hybrid density functionals are not applied to Q-Chem. Is it right? Or is my version (5.2) low to use this method?
