Preferred Label : Stokes shift;
IUPAC definition : The difference (usually in frequency units) between the spectral positions of the
band maxima (or the band origin) of the absorption and luminescence arising from the
same electronic transition. Generally, the luminescence occurring at a longer wavelength
than the absorption is stronger than the opposite. The latter may be called an anti-Stokes
shift.;
