In contrast, hydrates formed from O2(or an O3+ O2mixture) and Xe were observed to quickly dissociate when the pressure decreased to 0.1 MPa at a temperature of 0.1 \u00b0C.

This diameter is about 10% larger than that of oxygen molecules. Comparing the diameter ratio of ozone and oxygen to the cavity diameter (0.744 for ozone and 0.693 for oxygen), ozone shows a much better fit to the 512cages, even though both can occupy the cages. It is also empirically known and predicted by molecular dynamics-based free-energy simulations (cf. Miyoshi et al.J. Chem. Phys.2007,126, 234506) that, among various species that can fit into the cages, those having larger molar masses have lower equilibrium pressures. In view of this tendency, we can reasonably assume that ozone molecules are preferentially trapped in the 512cages compared to oxygen molecules."}],"container-title":["The Journal of Physical Chemistry B"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/pubs.acs.org\/doi\/pdf\/10.1021\/jp105031n","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,4,3]],"date-time":"2023-04-03T01:55:28Z","timestamp":1680486928000},"score":1,"resource":{"primary":{"URL":"https:\/\/pubs.acs.org\/doi\/10.1021\/jp105031n"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,8,13]]},"references-count":34,"journal-issue":{"issue":"35","published-print":{"date-parts":[[2010,9,9]]}},"alternative-id":["10.1021\/jp105031n"],"URL":"https:\/\/doi.org\/10.1021\/jp105031n","relation":{},"ISSN":["1520-6106","1520-5207"],"issn-type":[{"value":"1520-6106","type":"print"},{"value":"1520-5207","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,8,13]]}}}
