Abstract
Infrared fluorescence has been widely used to detect kinetic rates for chemical reactions and energy transfer. With the use of special gaseous and interference filters it is possible to detect numerous isotopic species or single excited states of atoms and molecules. Detailed state-to-state kinetic studies using laser excitation and infrared detection is an important new spectroscopic tool. Electronic-to-vibrational energy transfer events involving Br(2P1/2) transfer to diatomic and polyatomic molecular vibrations has been found to be very efficient. In many cases, the electronic-to-vibrational excitation produces population inversions among vibrational levels and many new laser transitions have also been observed. Isotopically selective photochemical studies in bromine have been carried out while continuously detecting the reaction enrichment using infrared vibrational chemiluminescence. The reaction of HC1 (v=2) with Br atoms has been studied. Infrared fluorescence from HC1 (v=1 and 2) is used to determine the extent of reaction versus deactivation pathways. Infrared fluorescence has become a powerful means of studying small molecule dynamics and offers many promising spectroscopic techniques for the future.
