We use terephthalic acid to observe visually the existence of OH radicals
in liquids. This method is introduced into plasma reacter to develop water
treatment technology.

OH Measurement using Laser-Induced Fluorescence (LIF)
Irradiating a certain ultraviolet ray to OH radicals leads to fluorescence.
We investigate the production of OH radicals in water-surface discharges
using an ultraviolet laser.
