(2013). New interpretation of proton and deuteron tunneling in 2'-methylacetophenone. Chemical Physics Letters, 586, 61-66. doi: 10.1016/j.cplett.2013.09.020The enol–keto transition rate constants in 2′-methylacetophenone observed by Grellmann et al. are calculated from first principles. The results reinterpret the proposed mechanism and show that proton tunneling is preceded by dissociation of a substrate-solvent complex rather than by rotamer interconversioneng© 2013 Elsevier B.V.
