Stokes Shift

The difference in wavelength between the absorption and emission maxima of a substance, typically due to vibrational energy level transitions.

📜

The statement of the theorem

Define

\nu_{abs}

as the frequency of maximum absorption and

\nu_{em}

as the frequency of maximum emission for a given transition. The Stokes Shift (

\Delta \nu_S

) is defined by the difference in these frequencies:\n

\Delta \nu_S = \nu_{em} - \nu_{abs}
