    "abstract": "We develop a simple thermodynamic model to describe the heat transfer\nmechanisms and generation of acoustic waves in photoacoustic Raman spectroscopy\nby small particulate suspensions in a gas. Using Langevin methods to describe\nthe thermal noise we study the signal and noise properties, and from the noise\nequivalent power we determine the minimum number density of the suspended\nparticles that can be detected. We find that for some relevant cases, as few as\n100 particles per cubic meter can be detected.",
