Matrix-isolation studies of non-covalent interactions: more sophisticated approaches
AbstractMatrix isolation is a powerful method to study non-covalent interactions, including hydrogen bonded species. The complexation effect is commonly analyzed by comparing vibrational spectra of the complex and the monomers. Most traditionally, molecular complexes in matrices are prepared by adding two species to the matrix gas and depositing the matrix at somewhat elevated temperatures and/or annealing the matrix after deposition. However, this general strategy is less suitable for the species that are difficult or impossible to prepare in the gas phase, for example, for highly reactive and unstable species. In addition, this method leads to relatively small amounts of the 1:1 complexes with an interference of monomers andlarger clusters.
