Photoacoustic Analysis in Condensed Matterve been reported until 1973. This delay in the improvement of the P. A. techniques is due to the fact that lasers are used as sources in such techniques, even if incoherent broad band light sources have shown to be useful sources for optical excitation.

Matrix-Isolation Spectroscopy of Small Metal Clusterspectra and gives valuable information on the gas phase properties. In addition particles which are produced only a low rates can easily be collected for spectroscopic measurements. The matrix isolation (MI) technique is therefore especially suitable for the spectroscopy of small clusters.

https://doi.org/10.1007/978-3-8348-9182-2ely and even one electron (or under vacuum conditions, one ion) can be detected, the technique can be used to make quantitative measurements of very small populations of the state-selected species. Counting of individual atoms has special meaning for detection of rare events.
