UV cavity enhanced absorption spectroscopy of the hydroxyl radical

Abstract:

We present the application of a continuous-wave ultra-violet tuneable light source for detection of the hydroxyl radical (OH) using cavity-enhanced absorption spectroscopy of the Q11(2) and Q21(2) absorption lines in the A2∑+(v′ = 0) ← X2Π3/2(v″ = 0) band at ca. 308 nm. A tuneable infra-red diode laser operating at 835 nm and either an Ar+ laser or a single frequency continuous-wave intracavity frequency-doubled diode laser, both operating at ca. 488 nm, were used to produce 0.1-0.5 μW of tun...
