    Notes: Abstract It has been shown experimentally that photoacoustic signals can be enhanced by introduction of a volatile liquid into the cell. Korpiun developed a theory which predicted the enhancement to be proportional to the mole fraction of the volatile component (y 0) in the gas phase. His theory is, however, based on a species conservation equation valid for dilute solutions only. We present a rigorous theory for predicting the enhancement of potoacoustic signal. Our theory shows the enhancement to be proportional toy 0/(1−y 0) which compares well with observations of Ganguly and Somasundaram.
