Lifetimes of excited states in TDDFT
Dear All,
I am working on a project involving excitations via TDDFT calculations. As such, I want to calculate the lifetime of the excited states. Can this analysis be done using Multiwfn?
The following is an explanation of what is needed for the analysis, taken from a previous paper.

Re: Lifetimes of excited states in TDDFT
You can easily manually calculate lifetime via this equation: τ≈1.5/(f * ν^2), where τ is lifetime in s, ν is excitation energy in cm^-1, f is the oscillator strength (dimensionless).

Thanks a lot!
Do you have a reference in which they used this method? I want to cite them in my work.
