Study confirms long-distance quantum tunnelling in thiourea
Validation for unusual proton-transfer process first observed 15 years ago
Scientists in Poland have confirmed that spontaneous thiol to thione hydrogen-atom transfer takes place in thiourea isolated in low-temperature matrices. Building on their earlier work on proton tunnelling in thiourea isolated in an argon matrix, Maciej Nowak and colleagues at the Polish Academy of Sciences have now investigated how matrix media and temperature influence the tunnelling rate.
