Selection Rules and the Intensity of Spectral Lines

  • G. Ludwig
Part of the Texts and Monographs in Physics book series (TEMP)


According to XI (1.17) the intensity of spectral lines is determined by the effect operator for the emission of a photon of frequency ω nm as follows:
$$ {\Delta ^1}{F_{n \to m}} = \Delta t\frac{{4\omega _{nm}^3}}{3}{E_n}\overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\rightharpoonup}$}}\to {d} \left( 0 \right)\cdot{E_m}\overset{\lower0.5em\hbox{$\smash{\scriptscriptstyle\rightharpoonup}$}}\to {d} \left( 0 \right){E_n} $$
