Broadband rotational coherent and anti-Stokes Raman scattering (CARS) and vibrational CARS measurements have been performed to determine the N2 temperature in a flame (1800–2000 K). Comparisons between these two CARS approaches indicate that, despite loss of signal strength with increasing temperature, rotational CARS is a potentially viable technique for flame-temperature measurements.
