Matrix Induced Changes in the Electronic Spectra of Isolated Atoms and Moleculeshence prevent successive reactions), but also inert enough not to alter its physical and chemical properties. The species, we are mostly dealing with in this chapter, will be metal atoms which are certainly very reactive and hence are widely studied in matrices.

The History of Matrix Isolation Spectroscopyroblems can be found, spectral features can be heightened, reactions can be slowed down, and phase changes investigated, reactive species stabilised and examined at leisure and a broad range of charge-transfer species investigated in detail.

Molecular Motion in Matricesare gas matrices beginning with the early studies on the vibrational-rotational spectra of small molecules trapped in the rare gases and concluding with the more recent studies in the low frequency spectral region.

Interpretation of Infrared and Raman Spectra of Trapped Molecular Impurities from Interaction Potentstal perfection was then to consider perturbations by defects in order to interpret optical and neutron scattering experimental observations in ionic crystals or to simulate migration mechanisms in metallic alloys. Extensive reviews of this theoretical approach can be found in Maradudin’s papers (1,2) and other Congress books (3–5).

Stable MoleculesThe principle of matrix isolation. is to obtain the spectrum of a species isolated in a large excess of an inert rigid matrix. In recent years the technique has almost always referred to the use of noble gases and certain other gases such as N., CH., SF. as matrix materials and hence it is essential to work at very low temperatures.

Non-Traditional Matrix Isolation: AdductsRecently we have searched for a technique which would allow the matrix isolation of molecules for Raman studies at room temperatures. Our previous far infrared research (WGF) utilized adamantane matricies for room temperature study. The adamantane matrix works very well for our far infrared studies but was not successful in our Raman studies, (1).
