Photochemistry of Matrix Isolated Molecules

Professor McMahon and his group synthesize stable precursor molecules and isolate them in the argon matrix. They then shine light on the argon matrix. Light energy is absorbed by the precursor molecules, thus forming the reactive molecules of interest. The frozen argon creates an environment for the molecules that is similar to the environment in outer space where they might be found! That is, a very cold environment with very little energy available.
