| Abstract: | A study has been made on the enhancement of photoacoustic and thermal lens spectroscopic signals. The affection of the thermophysics property of the solvent for photoacoustic and thermal lens spectroscopic signals has been discussed. A method of enhancing the photoacoustic signals for piezoelectric transducer is described. It is important to enhance the sensitivity for photoacoustic and thermal lens spectrometry in analytical chemistry. |
