Abstract
Different modifications of quartz enhanced photoacoustic spectroscopy (QEPAS) are discussed. An analysis of the signal-to-noise ratio for the generated photoacoustic signal gives hints for an optimized geometry of tuning fork and acoustic resonator. Furthermore, simultaneous or alternate photoacoustic and electrical driving is discussed, leading the way to new detection schemes that are capable of measuring changes in molecular relaxation dynamics.
