Infrared absorption spectroscopy and chemical kinetics of free radicals. [HCCN; CCH-H[sub 2] reaction; propargyl radical recombination]

During the last year, three projects were completed: a high resolution spectroscopic study of CH stretch of HCCN, measurement of rate constant of reaction between ethynyl (CCH) and H[sub 2] at 295-- 875 K, and measurement of recombination rate of propargyl (CH[sub 2]CCH) at room temperature. (DLC)
