Quantum yield is an important parameter in photochemistry. Diarylethene, as a kind of photochromic compound, is used in the experiment. We have validated the method for measuring the quantum yield in the photochemical reaction using the in-house made setup and applied this experiment to the comprehensive laboratory course. This experiment facilitates a better understanding of the principles and the applications, and the students' ability and interest to conduct an experiment are improved.

Key words: Quantum yield, Photochemistry reaction, Photochromic
