Abstract
In this paper coherent anti-Stokes Raman spectroscopy (CARS) measurements of gas temperature and density in an internal combustion (IC) engine are reported. Two coherent Raman techniques, CARS and inverse Raman spectroscopy (IRS), are also compared with spontaneous Raman scattering for use in internal combustion engine experiments. For sooting environments at engine pressures CARS is shown to have the greatest promise.
