Re: Increasing weight of exact HF-exchange in functional (option HFX) in TDDFT calculations

Thomas Pijper

Dear Evgeniy,

This is indeed possible. The BH&HLYP functional (which uses 50 % exact exchange) is actually a commonly used functional for TDDFT calculations. References that use this functional should be plentiful.

Kind regards,
