Reaction Path Following with Sparse Interpolation

Journal of Chemical Theory and Computation, 10(8), 2942–2949.

By: J. Nance n, E. Jakubikova n & C. Kelley n

TL;DR: This paper presents a method that isolates d < 3N - 6 molecular coordinates and continuously follows reaction paths on d-dimensional potential energy surfaces approximated by a Smolyak's sparse grid interpolation algorithm and presents simulation results for the isomerization of 2-butene with two, three, and six degrees of freedom.
