matrix isolation

[′mā·triks ‚i·sə′lā·shən]
(spectroscopy)
A spectroscopic technique in which reactive species can be characterized by maintaining them in a very cold, inert environment while they are examined by an absorption, electron-spin resonance, or laser excitation spectroscope.

Ozin's expertise in the spectroscopic characterization of clusters from his matrix isolation research led to a marvellously full understanding of the structure and reactivity of catalytic species in zeolites through techniques like vibrational spectroscopy, electron paramagnetic resonance, X-ray absorption fine structure analysis and photoelectron spectroscopy.
Kazuo Nakamoto pioneered the use of metal isotopes to elucidate the involvement of metals in low-frequency vibrations in metallic complexes and was among the first to use matrix isolation techniques to prepare and characterize unstable specie.
