PHOTOACOUSTIC SPECTROSCOPY OF CONDENSED MEDIA 
WITH A PHASE TRANSITION

UDC 535.16:534.341

The  gas-microphone  method  of recording a photoacoustic 
(PA) Rosencwaig-Herschow signal is extended theoretically 
for  consideration  of  material evaporation of a sample. 
For  an  excitation  source  of  constant  intensity  and 
exponential saturation of vapor concentration,  relations 
are  derived to describe the transient dynamics of the PA 
response.
