✦ Synopsis

The form of the emission spectrum induced by scattering of a generalised light pulse from LI single resonance is calculated from the known time dependence of sxh scattering. It is shown that the intensity of the scattered light is given by IF(Y$ = Ic;,;(v)12 Ls(v)lZ, where F(v), S(V), and G,!<v) are the probability amplitudes of the scattered light, the excitation source and the resonance at frequency V. The implications of this equation in the interpretation of scattering experiments is discussed. In particular, defining resonance Raman sgtterir?g s that scattering in which the scattered Ii&t has the same bandwidth as the exciting light, it is concluded that although resonance Ramnn and resonance fluorescence spectra correspond to limiting cases of resonance scattering spectra. spectra in intermediate cases cannot be resolved into a sum of a Raman spectrum and a resonance fluorescence spectrum.
