Radiation-induced transformations of acetaldehyde molecules at cryogenic temperatures: a matrix isolation study
Pavel V. Zasimov, Elizaveta V. Sanochkina, Vladimir I. Feldman
Abstract
CO˙ in the dark at 5 K was found only in Xe. This finding represents a prominent example of matrix-dependent chemical dynamics (probably, involving tunnelling), which deserves further theoretical studies. Probable mechanisms of acetaldehyde radiolysis and their implications for astrochemistry, atmospheric chemistry and low-temperature chemistry are discussed.
