I discuss how these quantum phenomena can be accounted for rigorously using Feynman path integrals in calculations of the equilibrium and kinetic isotope effects as well as of the temperature dependence of the rate constant. Because these calculations are extremely computationally demanding, special attention is devoted to increasing the computational efficiency by orders of magnitude by employing efficient path integral estimators. }, number={9}, journal={CHIMIA}, author={Vaníček, Jiří}, year={2011}, month={Sep.}, pages={715} }
