Laser Rayleigh thermometry is applied to a ducted non-premixed round jet flame of a nonsooting fuel mixture of methanol and hydrogen. The radial evolution of the temperature probability distribution function (pdf) is given for a single axial location. The first four moment of 70 temperature pdfs are reported. The temperature pdfs are compared with pdfs of a conserved scalar. Agreement is good on the centerline and at large radii. At intermediate radii, the flame zone, the double valued nature of the temperature-conserved scalar relationship does not allow an unambiguous resolution of discrepancies between reported pdfs of conserved scalars.
