Starting with a didactic insight to ESA based on simple molecular orbital and configuration considerations, the performance of various density functional theory functionals is tested to reveal the full vibronic ESA features of DSB at short and long probe delay times.engArtigo10.1063/1.4993216Acesso aberto2-s2.0-850248769022-s2.0-85024876902.pdf
