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?
