Each gas has a unique absorption wavelength, often described as its spectral fingerprint. This characteristic can be used to identify the gas. In photoacoustic spectroscopy, a laser modulated at a selected acoustic frequency irradiates the gas. Gas molecules absorb the laser energy and release heat, causing periodic expansion and contraction of the gas. The resulting pressure wave is detected as sound and converted into a concentration measurement.
