Charge transfer state

Can I use Multiwfn to find the intramolecular charge transfer (ICT) state using a Gaussian TDDFT result of 40 excited states? What is the parameter that I should look for to differentiate between the local excited state and the ICT state?

Thank you in advance.

Re: Charge transfer state

You can use Multiwfn to calculate delta-r index for all excited states, see Section 4.18.4 of Multiwfn manual for example. The larger the index, the larger the CT character.
