How to calculate excited-state geometric with gaussian methor?5 answersTo calculate excited-state geometry using the Gaussian method, a hybrid method called the Gaussian and Augmented-Plane-Wave (GAPW) method can be used. This method partitions the electronic density into hard and soft contributions, with the former expanded in a Gaussian basis and the latter expanded in plane-waves with a low energy cutoff. Additionally, a time-dependent density functional response theory (TD-DFRT) technique can be combined with the GAPW procedure to calculate excitation energies. Another approach is the Hartree-Fock theory, which can be used to calculate excited state energies by imposing orthogonality constraints and using even-tempered basis sets. For large systems, the Hylleraas-configuration-interaction (H-CI) method can be applied to determine the excited state geometry and energy.
