adcc (ADC-connect) is a python-based framework for performing the calculation of molecular spectra and electronically excited states based upon the algebraic-diagrammatic construction (ADC) approach.
Arbitrary host programs may be used to supply a self-consistent field (SCF) reference to start off the ADC calculation. Currently adcc comes with ready-to-use interfaces to four programs, namely pyscf, psi4, VeloxChem or molsturm. Adding other SCF codes or starting a calculation from statically computed data can be easily achieved.
