Reactions of trimethylsilyl azide with 3-trimethylsilyl-2-propynal and 2-propynal were studied. X-Ray analysis of the molecular structure of 4-trimethylsilyl-1H-1,2,3-triazole-5-carbaldehyde showed that the carbonyl group appears in the s-cis conform

The interaction of N/sub 2/- and NO-molecules of high kinetic energy colliding with a solid wall is investigated by two spectroscopic methods: laser induced fluorescence (LIF) and electron beam fluorescence (EBF). They allow one to measure the popula
