interfragment charge transfer during electron excitation (IFCT)

Hello

I have used Multiwfn according 4.18.16 Plot charge-transfer spectrum and calculate major characters
of all excited states... and analyzed TD-DFT calculations using IFCT from ORCA.

The information I am missing how Multiwfn calculate intensity of electronic transition at given wavelength?
How do you calculate molar absorption coefficient?

Thank you in advance for your reply

IFCT is not a method for analyzing intensity. The intensity of various electronic excitations is directly given by TDDFT calculation of ORCA.
