In this report the development of the use of clusters made of H2 or He as low temperature matrices for the study of chemically unstable species is described. Experiments on the Spectroscopy of alkali atoms, alkali dimers and alkali trimers are reported. One section describes the first experiments ever carried out on the NaHe exiplex and another the first detection and spectroscopy of a spin polarized Na trimer. Time resolved experiments on the above mentioned species are also described. As the temperature in these newly developed matrices is substantially lower than in other commonly used matrices, it is anticipated that spectroscopy in cluster will find many applications in the study of chemical metastability. This has important implications for the whole field of high energy materials for rocket propulsion.
