Abstract

Nuclear magnetic resonance (NMR) of some nuclei (e.g. ¹H, ¹³C, ¹⁹F, ²⁹Si and ³¹P) gives strong signals which allow one for analytical investigations of gaseous compounds. The other magnetic nuclei have low natural abundance or/and contain electric quadrupole moments and therefore they are less suitable for such NMR applications. In our laboratory we have developed new experimental techniques which permit us to monitor several micrograms of chemical compounds in the gas phase. For the first time we have observed ¹⁷O and ³³S NMR spectra of gaseous compounds at the natural abundance as a function of density. We have also found density-dependent spin-spin coupling constants in many molecules. We could extend our gas-phase studies on molecules which exhibit strong intermolecular interactions and are liquids at room temperature. All the latter NMR experimental results obtained for gaseous mixtures are reviewed in this paper.
