Stokes resonance Raman scattering

Figure 6.1 Spectroscopic transitions for Rayleigh scattering, Stokes and anti-Stokes Raman scattering, and resonance Raman scattering.

Figure Bl.2.5. Comparison of several light seattering processes, (a) Rayleigh scattering, (b) Stokes and anti-Stokes Raman scattering, (c) pre-resonance Raman scattering, (d) resonance Raman scattering and (e) fluorescence where, unlike resonance Raman scattering, vibrational relaxation in the excited state takes place.

At resonance with an electric dipole allowed transition, the Stokes resonance Raman scattering, I(tt/2), associated with a single totally symmetric mode and its overtones is proportional to... 

The nonlinear optical properties are determined using resonance Raman scattering, coherent antistokes Raman scattering and coherent stokes Raman scattering. The two-photon polarizability is found to be very large in these materials. General... 

In order to extend the range of 2laser excitation, both CARS (Coherent Anti-Stokes Raman Scattering) and CSRS (Coherent Stokes Raman Scattering) are used. In both cases <03 = 2003 -U2 In the CARS mode 0)3 > wj > (03 in the CSRS mode <02 > (1)3. One-photon resonance effects are the same in both cases as described later. Phase matching is also the same in both cases with 3 = 2 ...

In transparent and optically inactive media, where the input frequencies are away from any electronic transition frequencies, and only the molecular ground state is populated, the selection rules of both resonant coherent and spontaneous Raman scattering are identical... 

Fig. 7.1. Two equivalent ROA experiments involving Stokes vibrational Raman scattering at angular frequency oj — ojv in incident light of angular frequency oj far from resonance, a The ICP ROA experiment measures JR - JL, where JR and JL are the scattered intensities (shown here as unpolarized) in right- and left-circularly polarized incident light, respectively, b The SCP ROA experiment measures hi-h., where Jr and JL are the intensities of the right- and left-circularly polarized components, respectively, of the scattered light using incident light of fixed polarization (shown here as unpolarized)...
