Deep inelastic neutron scattering (DINS) experiments can measure this effect. Thus, the nuclear quantum kinetic energy can be probed directly in both ordered and disordered samples. However, the relation between the quantum kinetic energy and the atomic environment is a very indirect one, and cross-validation with theoretical modeling is therefore urgently needed. Here, we use state of the art path integral molecular dynamics techniques to compute the kinetic energy of hydrogen and oxygen nuclei in liquid, solid, and gas-phase water close to the triple point, comparing three different interatomic potentials and validating our results against equilibrium isotope fractionation measurements. We will then show how accurate simulations can draw a link between extremely precise fractionation experiments and DINS, therefore establishing a reliable benchmark for future measurements and providing key insights to increase further the accuracy of interatomic potentials for water.","lang":"eng"}],"oa_version":"None","date_published":"2016-06-16T00:00:00Z","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","author":[{"id":"cbe3cda4-d82c-11eb-8dc7-8ff94289fcc9","orcid":"0000-0002-3584-9632","last_name":"Cheng","first_name":"Bingqing","full_name":"Cheng, Bingqing"},{"last_name":"Behler","first_name":"Jörg","full_name":"Behler, Jörg"},{"full_name":"Ceriotti, Michele","last_name":"Ceriotti","first_name":"Michele"}],"external_id":{"pmid":["27203358"]},"date_updated":"2023-02-23T14:04:49Z","quality_controlled":"1","doi":"10.1021/acs.jpclett.6b00729","_id":"9681","year":"2016","scopus_import":"1","volume":7,"extern":"1","citation":{"mla":"Cheng, Bingqing, et al. “Nuclear Quantum Effects in Water at the Triple Point: Using Theory as a Link between Experiments.” <i>The Journal of Physical Chemistry Letters</i>, vol. 7, no. 12, American Chemical Society, 2016, pp. 2210–15, doi:<a href=\"https://doi.org/10.1021/acs.jpclett.6b00729\">10.1021/acs.jpclett.6b00729</a>.","ista":"Cheng B, Behler J, Ceriotti M. 2016.
