摘要:
A discussion on using the phase shifts of the photoacoustic signal of a monophase sample for resolving its overlapping absorption peaks is presented. It is experimentally shown that the method is simple and useful. And the time delay which includes the nonradiative relaxation time, the thermal-diffusion time and the time of generating the acoustic signal is calculated. This is demonstrated using L-Tryptophan compounds.
