A method for the calibration of OH temperature measurements using lase
r-induced fluorescence is demonstrated. The technique depends on the t
hermal dissociation of water vapor in a furnace. The calibration was d
emonstrated for the excitation of the A2SIGMA+(upsilon' = 3) - X2PI(up
silon'' = 0) band with a tunable KrF laser. Consistent discrepancies o
f 3% between calculated and measured temperatures with a standard devi
ation of 8% were observed.
