WebJul 20, 2024 · This is the well-known Strickler-Berg equation which connects both the absorption and emission spectra for determining the average lifetimes of the molecules in their excited states. One must observe that as a special case, if the absorption and emission spectra are sharp and take place at the same frequency, this equation gives the same … WebDec 11, 2006 · The Strickler–Berg equation has been rarely applied to estimate the k r values of short-lived species such as radical ions, free radicals, and carbenes in the excited states. There are a few reports using this equation to calculate the S 2 → S 0 transitions [21] .
WebThe decay channels of the singlet excited states of halogenated sulfonamide tetraphenylporphyrins, chlorins and bacteriochlorins were fully characterized. It was found that the radiative rates and the internal conversion rates of the bacteriochlorins are lower than expected from the Strickler–Berg equation and from the energy-gap law, … WebSep 3, 2015 · Radiative transitions between the three lowest-lying electronic states of molecular oxygen have long provided a model to study how collision-dependent perturbations influence forbidden processes.
