Abstract

The coherent anti-Stokes Raman spectroscopy spectrum of H₂o has been measured in a heated optical cell and in laboratory flames. Comparisons of the experimental spectra with a theoretical model have been used to infer information about the unknown Raman linewidths of H₂O. In the test cell, excellent agreement has been obtained between theory and experiment in terms of physically realistic linewidths. Agreement between experiment and theory in laboratory flames is also good.
