Add to ORKGWe demonstrate a novel method to spectroscopically detect and identify trace gases. Micromechanical photother-mal spectroscopy (MPS) with functionalized sorbent materials provides trace gas spectra in an optical interaction length of only a few micrometers. We use microcavity interferometry to read out displacements as low as 25 fm
Laser absorption spectroscopy utilizes a tunable infrared source, providing the necessary selectivit...
