Fluorescence

Fluorescence occurs when a molecule in an electronically excited state undergoes vibrational relaxation before decaying back down to the ground electronic state. The fluorescent emission will be lower in energy (longer in wavelength) than the excitation energy.

@@PhysicalChemistry Professor, How would we choose the suitable excitation wavelength for a new molecule for measuring its emission spectra?
