Abstract
Detection of KCl and KOH molecules using direct absorption measurement is a difficult task as the molecular spectra at UV wavelengths is broad and interfering absorption caused by other molecules is evident. In addition, measurement of small concentrations requires a large interaction length due to small absorption cofficient. It was shown that much more selective and sensitive measurement will be achieved using the UV pulse to dissociate K atom from KCl molecule and using atomic absorption spectroscopy to detect the temporally increased atomic concentration. [1] Atomic spectroscopy yields to increased sensitivity and selectivity due to narrow linewidth of atomic spectrum.
