摘要
The radiationless relaxation process of excited molecules has developed as the basis for many laser photothermal spectroscopies. For example, laser photoacoustic spectrometry, laser thermal lens spectrometry, laser photothermal deflection spectrometry, laser photothermal refraction spectrometry and laser photothermal interference spectrometry have been applied to analytical chemistry and evolved into a kind of high sensitivity and high space resolution absorption spectrometries.
