Diacetylene, resonance CARS

As an example of resonance CARS studies in solids, for which a linear resonance Raman study has been impossible to perform because of simultaneous strong luminescence, we consider here investigations on colour zones in substituted diacetylene crystals... 

Figure 6.1-23 Resonance CARS spectra of a substituted diacetylene single crystal (FBS-DA) at 10 K. The pump wavelength Xp used is labeled for each spectrum, (a) and (b) show CARS spectra of the P-colour zone, and (c)-(l) those for the Y-coiour zone. Spectra on the left side correspond to the C=C stretching region, and those on the right side to the C=C stretching region. For further details, see text (Materny and Kiefer, 1992b).
