The hydroxyl radical(OH) and oxygen atom(O) play important roles in atmospheric chemistry, surface treatment and chemical decontamination. The present work reports the measurement of OH and O in atmospheric pressure plasma jet by optical emission spectroscopy. The OH and O are observed in discharges of the H2O/O2/Ar mixture. The effects of discharge power and O2 addition in discharge system on the emission intensity of OH and O are studied. By comparing the measured emission spectrum of OH with that simulated from Lifbase data, the rotational temperature is evaluated for OH.It is shown that the rotational temperature of OH increase with the increase of discharge power,and decrease with the increase of discharge gas flow rate.
