Intermediate case radiationless decay: the excited state dynamics of pyrazine
TLDR
In this article, the authors reported new measurements of the non-exponential fluorescence decay of pyrazine, covering the time range 0.1-200 ns, and showed that the triplet component of the mixed singlet-triplet levels does increase with increasing triplet density of states, and the effective density of triplet levels determined from their experimental data exceeds the theoretical density of vibrational levels.About:

Perturbations between Electronic States in Aromatic and Heteroaromatic Molecules
TL;DR: In this article, the authors compared the low-temperature electronic spectra of several aromatic azines in regions of nπ* and ππ* overlap and concluded that transitions to the higher energy state are generally quite diffuse compared with those to the lower.
