Atomic Chemistry.
Abstract
Several methods were developed for the study of low temperature reactions of high temperature species applicable to a broad range of substrates. The method employs a high vacuum to separate the high temperature zone from the low temperature reaction zone, flight across the the vacuum of the high temperature species bringing them in contact with the substrates on the low temperature surface. A variety of high temperature sources have been employed. Major attention has been given to the examination of carbon molecules. Thermal vaporization provides ground state populations of C1, C2, and C3. Arc vaporizations result in high proportions of these same molecules in their metastable states. The chemistries of all these molecules have been studied with a wide variety of organic and inorganic substrates, including alkanes, alkenes, alkynes, alcohols, carbonyl compounds, alkyl halides, sulfides, etc., providing a fairly complete description of the reactions which take place and their mechanisms. This method has been extended in a preliminary way to B, Si, Mg and further in the continuing program. The major objective is the exploration of the untouched areas of the reactions of all the atomic systems, and other small high temperature molecules. (Author)
