利用脉冲光声技术,研究液相光化学和光生物化学反应过程,在基本理论和实验技术两方面都有了重要的发展,为直接测定其反应动力学和热力学参量提供有效的方法,并广泛应用于测定各种有机化合物、配合物和动植物蛋白质分子在溶液中的光解反应,对光解反应引起的焓变、结构体积变化以及瞬态中间产物的寿命和量子产率给出丰富的信息。本文对有关领域在国内外的主要进展作了简要的介绍,并提出今后需要研究的一些问题。 The use of pulsed photoacoustic technology to study the liquid-phase photochemical and photobiochemical reactions has important developments in both basic theory and experimental techniques, and provides an effective method for direct determination of reaction kinetics and thermodynamic parameters. It is widely used in Determination of various organic compounds, complexes and animal and plant protein molecules in solution photolysis reaction, the enthalpy change caused by the photolytic reaction, the structural volume changes and transient intermediate products and quantum yield of life give rich information. This article gives a brief introduction of major developments at home and abroad in related fields and puts forward some issues that need to be studied in the future.
