Infrared and Raman Matrix Isolation Spectroscopy
Infrared spectroscopy of matrix-isolated substances was first reported by Whittle, Dows and Pimentel (1) in 1954, and the subsequent development of the technique owes much to Pimentel and his co-workers. Despite an early study of methane in a krypton matrix (2), using a mercury arc source, matrix isolation Raman spectroscopy had to await the advent of readily available gas laser sources. Rapid development has followed the pioneering paper by Shirk and Claassen (3). More recently, the use of Fourier transform infrared spectrometers and tunable infrared laser sources has provided higher resolution capabilities and revealed previously unsuspected fine structure on many matrix bands.
