Conclusion • Corrected mode description of inversion • ~250 cm-1vs ~100 cm-1 • DFT based methods lead to erroneous results • Significant change in geometry from the singlet states • EOM-CCSD based methods best for the excited states of 2CHO
Future Work • Multiconfigurational and explicitly multireference methods for excited states • CASSCF • NEVPT2 • Expansion of EOM-EE-CCSD results in a triple zeta basis set
