Time-resolved intracavity laser absorption spectroscopy of free radicals

Intracavity Laser Absorption Spectroscopy (ICLAS) combined with flash photolysis has been used over 20 past years as a powerful tool for time and quantum state resolved spectroscopy of vibrational relaxation, elementary gas phase chemical reaction, heterogeneous decay, rotational temperature and absorption cross section measurements, and in some cases for spectroscopic identification of free radicals as well. Detailed description of experimental setups and methods of ICLAS spectra recording and processing enable to critically evaluate data obtained by ICLAS technique for NH2, PH2, HCO, HSO, HNO, HO2, CH3O2 radicals in visible and near IR region.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
