Quantum mechanical tunneling is essential to understanding chemical reactivity

PR Schreiner - Trends in Chemistry, 2020 - cell.com
Quantum mechanical tunneling is a consequence of the wave nature of particles that implies
that a particle can penetrate a potential energy barrier even though there is insufficient …

Heavy‐Atom Tunneling in Organic Reactions

C Castro, WL Karney - Angewandte Chemie, 2020 - Wiley Online Library
In the past few years, numerous investigations have been reported on the role of heavy‐

Competitive nitrogen versus carbon tunneling

CM Nunes, AK Eckhardt, I Reva, R Fausto… - Journal of the …, 2019 - ACS Publications
Quantum mechanical tunneling (QMT) of heavy atoms like carbon or nitrogen has been
considered very unlikely for the longest time, but recent evidence suggests that heavy-atom …

Switch chemistry at cryogenic conditions: quantum tunnelling under electric fields

O Kirshenboim, A Frenklah, S Kozuch - Chemical Science, 2021 - pubs.rsc.org
While the influence of intramolecular electric fields is a known feature in enzymes, the use of
oriented external electric fields (EEF) to enhance or inhibit molecular reactivity is a …

Heavy‐Atom Quantum Tunnelling in Spin Crossovers of Nitrenes

ER Heller, JO Richardson - Angewandte Chemie International …, 2022 - Wiley Online Library
We simulate two recent matrix‐isolation experiments at cryogenic temperatures, in which a
nitrene undergoes spin crossover from its triplet state to a singlet state via quantum …

Geometry-controlled reactivity and dynamics in organic molecules

PK Saha, T Tran Ngoc, PR McGonigal, JF Teichert - Nature Synthesis, 2024 - nature.com
It is well established that strain in organic molecules is linked to having nonideal bond
