Abstract

The chemical application of laser spectroscopies[1] are extended to species isolated in an argon matrix. This environment has the advantages of being transparent over a wide spectral range and allowing the measurement of reactive and insoluble chromophores. Matrix samples are necessarily prepared in vacuo, but are subsequently “injected' into LHe in our specially developed apparatus [2] to provide the low temperatures (<4 K) and high refrigerant powers needed to take full advantage of laser selective techniques.
