We describe the first implementation of narrow-band coherent Rayleigh scattering (CRS) for high spectral resolution of CRS line shapes. Using intensities in the 109 W/cm2 range we find that the measured line shapes of CO2, N2 and Xe gases at room temperature are in good agreement with a CRS model that assumes weakly perturbing fields. We compare our results with broadband CRS and discuss the importance of phase-matching requirements for narrow-band CRS. Finally, we show that a spectral narrowing in the CRS profile is predicted at intensities that are approximately an order of magnitude greater than those used in our experiments.
