... The quantum yield is determined using the comparative method, which relies on the use of fluorescence standards with known fluorescence quantum yields (Rhodamine 6G; QY=95% in our case). We use the equation: QYx=QYs * [Ax/As]*[Fs/Fx]*[nx/ns]2 where Ax and As are the integrated area under the correct ...

Franck–Condon principle
The Franck–Condon principle is a rule in spectroscopy and quantum chemistry that explains the intensity of vibronic transitions. Vibronic transitions are the simultaneous changes in electronic and vibrational energy levels of a molecule due to the absorption or emission of a photon of the appropriate energy. The principle states that during an electronic transition, a change from one vibrational energy level to another will be more likely to happen if the two vibrational wave functions overlap more significantly.
