Summary:The feasibility of applying optoacoustic spectroscopy for the detection of short-lived species is demonstrated. Several reaction intermediates were observed in a dc discharge. The method was shown to be significantly more sensitive than direct absorption and is complementary to existing techniques for the monitoring of transient species.
