Laser Raman spectroscopy has been demonstrated to be a useful technique for making temperature measurements in single‐phase water vapor at atomospheric pressure over the temperature range 393–593 K. It has also been demonstrated that laser Raman spectroscopy can measure water vapor temperatures in non‐equilibrium dispersed two‐phase flow over the temperature range 393‐353 K in spite of large Rayleigh and Mie scattering from droplets. Estimated temperature uncertainties are ±15 K for single‐phase and ±22 K for two‐phase flows.
