An automated method to find transition states using chemical dynamics simulations

E Martínez‐Núñez - Journal of computational chemistry, 2015 - Wiley Online Library
A procedure to automatically find the transition states (TSs) of a molecular system (MS) is
proposed. It has two components: high‐energy chemical dynamics simulations (CDS), and …

An automated transition state search using classical trajectories initialized at multiple minima

E Martínez-Núñez - Physical Chemistry Chemical Physics, 2015 - pubs.rsc.org
Very recently, we proposed an automated method for finding transition states of chemical
reactions using dynamics simulations; the method has been termed Transition State Search …

Intramolecular vibrational energy redistribution and the quantum ergodicity transition: a phase space perspective

S Karmakar, S Keshavamurthy - Physical Chemistry Chemical Physics, 2020 - pubs.rsc.org
Intramolecular vibrational energy redistribution (IVR) impacts the dynamics of reactions in a
profound way. Theoretical and experimental studies are increasingly indicating that …

Direct Dynamics Trajectories Demonstrate Dynamic Matching and Nonstatistical Radical Pair Intermediates during Fe-Oxo-Mediated C–H Functionalization Reactions

J Joy, DH Ess - Journal of the American Chemical Society, 2023 - ACS Publications

SR Hare, LA Bratholm, DR Glowacki… - Chemical science, 2019 - pubs.rsc.org
Most chemical transformations (reactions or conformational changes) that are of interest to
researchers have many degrees of freedom, usually too many to visualize without reducing …

[HTML][HTML] Cryptic post-transition state bifurcations that reduce the efficiency of lactone-forming Rh-carbenoid C–H insertions

SR Hare, DJ Tantillo - Chemical science, 2017 - pubs.rsc.org
Byproducts of chemical reactions are generally thought to result from the competition
