Study Notes
Fluorescence Spectroscopy
- Fluorescence spectroscopy analyzes fluorescence from a sample
- Primary concern is to measure the intensity of fluorescence emitted by a sample
- During fluorescence spectroscopy, the species (molecule) undergoes excitation and relaxation
- The ground electronic state of the species is the lowest energy state
- The excited molecule loses vibrational energy through non-radiative relaxation, which causes it to transition back to the ground electronic state, emitting a photon of lower energy
