Detection of specific molecules in the atmosphere is motivated by the need for monitoring the emission of industrial pollutants. CO2-laser photoacoustic (PA) spectroscopy was used here to obtain coincidence spectra of the vapours of three organic solvents: trichloroethylene (TCE), benzene, and dioxan. Spectra of coincidences were obtained as a function of total pressure, adding dry air to the vapour of the solvents up to 1000 mbar. A narrow cavity photoacoustic cell with window acoustic buffers was built for improved sensitivity, and is reported here. The vapour molecules studied do have some significant absorption in the CO2-laser region, or close to it, but that fact does not necessarily lead to usable coincidences with the narrow laser lines. The results reveal several prominent coincidences that can be used for practical purposes, especially in the case of trichloroethylene.
