Abstract

The theory of the photoacoustic signal from a gas-filled sample cell is reconsidered, and it is shown that the results obtained from one-dimensional models are more generally applicable. In particular, for typical experimental conditions, a simple modification of the composite piston model presented previously gives an expression for the signal in any nonresonant cell.
