HIGH RESOLUTION INFRARED SPECTROSCOPY OF TRANSIENT MOLECULES

In this review the topics of instrumentation (I), high temperature molecules (II D), free radicals (II E), and a few arbitrary selections from the semi­ stable molecule category (II B) are discussed. Furthermore, only gas-phase vibration-rotation transitions of ground electronic states are included. Such topics as infrared electronic transitions [e.g. SiC (1 )], pure rotational transitions [e.g. OR (2, 3)], and vibration-rotation transitions in excited electronic states [e.g. aId state of SO (4)] are excluded. The detection of
