NEO-MP2 energies and annihilation rates were calculated for PsH, and the effects of basis set size on correlation energies captured with the NEO-MP2 and NEO-FCI methods are compared and discussed. Equilibrium geometries and vibrational energy levels were computed for the LiX and e+LiX (X = H, F, Cl) systems at the MP2 and NEO-MP2 levels. It was found that anharmonicity plays a significant role, specifically in the differences between the vibrational energy levels of the LiX and e+LiX systems. The implications of these results with respect to VFR for these systems is discussed.","brand":"WoB","offers":[{"title":"US \/ NEW \/ INGRAM","offer_id":53251822944529,"sku":"NIN9781249590958","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9781249590958.jpg?v=1773592525","url":"https:\/\/www.worldofbooks.com\/en-gb\/products\/general-quantum-mechanical-method-to-predict-positron-spectroscopy-book-paul-e-adamson-9781249590958","provider":"World of Books ","version":"1.0","type":"link"}
