激光光解时间分辩红外发射谱仪

A Time-Resolved FTIR Emission Spectrometer Used for Photochemical Reactions

摘要: 本文详细介绍了我们自行研制的激光光解时间分辨富里叶红外发射谱仪的基本工作原理及其构造,及在诸如光解动力学、自由基(原子)与分子反应、振动能的碰撞传能等方面的应用.由于获得激发态产物的振转分布,因此可以得到上述过程的许多动力学方面信息.

Abstract: A high-resolution, time-resolved Fourier transform infrared （FTIR）emission spectrometer to study photochemical reactions has been established. The capability to obtain vibrational and rotational-state details of the excited products reveals intriguity new features about the dynamics of the processes. This paper systematically introduces the principle and structure. of this set-up and its application in such fields as photofragmentation, radical（atom）—molecule reaction and vibrational evergy transfer.
