The validity of arbitrarily increasing the mass of the exchanged atom when calculating reduced-dimensionality three-dimensional quantum cross sections for heavy-heavy-light reactions has been investigated by considering, as a case study, the Li + FH+LiF+ H system. This exchanged-atom isotopic effect

## Abstract A convenient approach to compute kinetic isotope effects (KIEs) in condensed phase chemical reactions is via path integrals (PIs). Usually, the primitive approximation is used in PI simulations, although such quantum simulations are computationally demanding. The efficiency of PI simula
## Abstract The nucleotides of DNA and RNA are joined by phosphodiester linkages whose synthesis and hydrolysis are catalyzed by numerous essential enzymes. Two prominent mechanisms have been proposed for RNA and protein enzyme catalyzed cleavage of phosphodiester bonds in RNA: (a) __intra__molecul
