“…There are various attempts in the literature reporting nonadiabatic correction of the Albrecht theory. Here, we present a perturbational approach which was successfully applied to porphyrins first by Shelnutt and Shea [17] and in a more quantitative way by Unger et al [23] and SchweitzerStenner et al [24]. While it still expresses the molecular eigenstates in terms of crude Born-Oppenheimer vibronic states, it allows for vibronic coupling between vibronic states within the same as well as between different electronic states.…”

“…The analysis was carried out by Dr. Esko Unger in the author's former research group at the University of Bremen and has not been published. The theoretical approach used for this analysis has been described by Unger et al [62]. 1 -, 2 -, and 2 -modes are predominantly though not exclusively Herzberg-Teller active; this type of coupling mixes components of different electronic states ( , with , , in our case).…”

“…If this was the case, the band would be practically undetectable in the entire preresonance and resonance regions of the Q-band, contrary to what the excitation profile in Figure 5 suggests. In reality, the ] 4 -band gains considerable Raman activity from Herzberg-Teller coupling [19,60,62,63].…”

“…Порфирин никеля NiP и свободный (без атома металла) порфин Н 2 Р были синтезированы с по-мощью методик, известных из литературы [23]. Образцы для измерений представляли собой поликристалличе-ские слои NiP толщиной около 30 nm, приготовленные in situ путем термического испарения порошка порфи-рина из танталового тигля ячейки Кнудсена и осаждения на чистую поверхность медной пластинки.…”
