摘要: Results of a line shape and resonance light scattering study the S1←S0 S2←S0 electronic transitions azulene in isopentane cyclohexane are reported. The results analyzed using two different non‐Markovian master equations that make assumptions about statistical properties bath. For both these origin we find solution dynamics fall so‐called intermediate modulation regime. If exponential decay is assumed for bath correlation function obtain time 25 fs transition 13 at room temperature. From frequency dependence ratio fluorescence to Raman yields calculate an excited state lifetime 1.4±0.2 ps parameters derived from analysis, irrespective which equation used.
