title: Optoacoustic detection of NO(2) using a pulsed dye laser.
abstract: Using a pulsed dye laser and a nonresonant optoacoustic detector, the absorption spectrum of NO(2) has been measured in the spectral region of 480-625 nm at various cell pressures and at various concentrations in air. The results of the measurements as a function of NO(2) concentration in air demonstrate the detection capability of the system. An extrapolated sensitivity of 4 ppb NO(2)/W of laser power has been achieved.
