The design of new NLO molecules and materials has benefited from the development of computational tools to analyze the relationship between the electronic structure of molecules and their optical response. In this paper, we present a new means to analyze the response property through the partition of NLOPs in terms of orbital contributions (PNOC). This tool can be used to obtain a real-space representation of the NLOPs, providing a powerful visualization aid to connect the magnitude of the optical property with some parts of the molecule. Unlike other methods to analyze NLOPs, the PNOC decomposes the optical property into orbitals of the unperturbed system, furnishing this method with the ability to assess the performance of single- and multi-determinant electronic structure methods. PNOC can be also used to design small basis sets for an accurate description of large systems, saving a substantial amount of computer time for the calculation of optical properties" , "dc.description.abstract": "This research has been funded by Spanish MINECO/FEDER Projects CTQ2014-52525-P and EUIN2017-88605, the Catalan DIUE 2014SGR931 and IKERBASQUE" , "dc.format.extent": "12 p." , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "Royal Society of Chemistry (RSC)" , "dc.relation": "MINECO/PN 2011-2015/CTQ2014-52525-P" , "dc.relation.isformatof": "Versió postprint del document publicat a: https://doi.org/10.1039/C9CP02662B" , "dc.relation.ispartof": "© Physical Chemistry Chemical Physics, 2018, vol. 21, núm. 28, p. 15380-15391" , "dc.relation.ispartofseries": "Articles publicats (D-Q)" , "dc.rights": "Tots els drets reservats" , "dc.source": "Sitkiewicz, Sebastian P.
