SUMMARY

The discussion centers on the impact of recoil effects on Einstein's coefficients, which represent the probabilities of light absorption and emission by atoms or molecules. Participants explore how neglecting recoil could alter these coefficients, referencing Robert Hilborn's work on the subject. Key terms such as cross sections, f values, and dipole moments are highlighted as critical factors in understanding the interaction between light and matter. The consensus indicates that recoil effects must be considered for accurate modeling of these probabilities.

What would happen with Einstein's coefficients if we wouldn't neglect the recoil effects?

Assuming that Einstein's coefficients are basically probabilities of absorption or emission of light by an atom or molecule, would recoil influence those probabilities?

Robert Hilborn, Einstein coefficients, cross sections, f values, dipole moments, and all that
