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 (γ0) 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 to γ0/(1-γ0) which compares well with observations of Ganguly and Somasundaram.
