The first study of temperature dependent photochemical reactions in the microwave field is reported. Two different photochemical processes, temperature dependent solvent effects in the Norrish type II reaction and the photo-Fries reaction, were investigated under various thermal conditions including microwave heating. The former process exhibited a linear and reliable temperature dependence which served for the estimation of the microwave superheating effects in four different solvents. Their magnitudes were in a perfect agreement with the measured temperature enhancements. Thus, this photochemical system is proposed as a reliable molecular photochemical thermometer. The latter photochemical reaction studied showed a non-linear temperature dependence. All chemical changes in the microwave field were rationalized as a consequence of thermal effects.
