Abstract
A new method for performing high-frequency, visible FM spectroscopy by using low-frequency detection is demonstrated. By using this technique, a detection limit of 323 μTorr m (path length) has been established for atmospheric-pressure-broadened NO2. This corresponds to a differential absorption of 1.0 × 10−5.
