    TheoDORE

    TheoDORE

    Theoretical Density, Orbital Relaxation and Exciton analysis

    The TheoDORE (Theoretical Density, Orbital Relaxation and Exciton analysis) package is a general purpose program suite for the analysis of excited states obtained from quantum chemical excited state calculations. Wavefunction analysis is based on state and transition density matrices, which provides a unified formalism applicable independent of the wavefunction model. TheoDORE is interfaced to a number of quantum chemical programs (Q-Chem, Columbus, Turbomole, ...) and can be used for a wide range of excited state methods (MR-CI, ADC, CC, TDDFT). It is written in a modular fashion to allow for an easy extension of these capabilities. Code development moved to github: https://github.com/felixplasser/theodore-qc
