text: Spontaneous Raman scattering is typically very weak; as a result, for many years the main difficulty in collecting Raman spectra was separating the weak inelastically scattered light from the intense Rayleigh scattered laser light (referred to as "laser rejection").
text: Raman scattering is usually extremely weak, of the order of 1 in 10 million photons that hit a sample are scattered with the loss (Stokes) or gain (anti-Stokes) of energy because of changes in vibrational energy of the molecules in the sample.
text: Raman scattering is very weak and is typically much smaller than the Rayleigh scattered light, so great care must be taken extract the Raman signal from the Rayleigh signal, particularly for small frequency shifts.
