Matrix isolation spectrometric characterization

Some methods of characterization of high-temperature molecules rely on direct flow-system vapor-phase measurements, for example, mass spectrometric and electron diffraction studies. Matrix isolation also plays a significant role in that vapor species may be trapped by rapid quenching. The most unambiguous results have perhaps been drawn from a combination of the two approaches.

Examination of neutral transition-metal oxides would circumvent the particular restrictions associated with the net Coulomb charges of the species. In the gas phase, however, the reactivity of neutral transition-metal species is quite difficult to study, and, even more importantly, characterization of reaction products is often impossible. While matrix-isolation studies can fill this gap to some extent, these experiments are less general with respect to the variability in the range of metals, substrates, and possible ligands than are salient mass spectrometric investigations. In the context of catalysis, the low temperatures of matrix studies, in conjunction with the thermal coupling to the dense bulk material of the matrices, limit the scope of thermally driven reactions that can be probed using this technique.
