Abstract:

A technique for computer reconstruction of the pressure signal shape from the pulse microphone signal is offered. It is shown that the time of collisional relaxation of molecules from the excited state to the ground one can be measured on its basis with the use of a time-resolved photoacoustic spectrometer.

Keywords:

pulse photoacoustic signal, laser molecular spectroscopy, collisional relaxation
