what is the type of PCM-TDDFT you are interested in?
Is this relaxed or unrelaxed PCM-TDDFT?

Firefly is only capable to perform either fully unrelaxed PCM-TDDFT
(for vertical excitation spectra) or fully relaxed PCM-TDDFT
(for vertical emission spectra).

You need to specify RSOLV and EPS for these calculations.
There is no need to specify EPSINF.

Kind regards,
Alex Granovsky
