photoacoustic spectroscopy
A spectroscopic technique based on the @P04575@. A photoacoustic spectrum consists of a plot of the intensity of the acoustic signal detected by a microphone or a 'piezoelectric' detector, against the excitation @W06659@ or another quantity related to the photon energy of the modulated excitation.
