The atomic charges and charge-flow parameters are calculated directly by ab\u00a0initio methods. The performance for liquid-state properties of models that include 1-bond, 2-bond, and 3-bond charge-flow is probed for chloroform and acetonitrile through measurements of dielectric constants, dipole moments, and infrared spectra. The results indicate that models allowing charge-flow only between directly bonded atom pairs (1-bond) lead to significant deviations compared to models incorporating 2- and 3-bond contributions, suggesting that restricting charge-flow solely between directly bonded atom pairs omits important physical contributions. In addition, modeling polarizability via charge-flow inherently leads to an anisotropy description of the molecular polarizability tensor, with the level of anisotropy constituting a major component in the electrostatic response. The results also suggest that modeling the molecular polarizability by only charge-flow tends to overestimate the electric polarization and, thus, indicate that combinations of rank-0 and rank-1 polarizability are required for an accurate modeling of the electric response.<\/jats:p>","DOI":"10.1063\/5.0278180","type":"journal-article","created":{"date-parts":[[2025,8,15]],"date-time":"2025-08-15T09:50:17Z","timestamp":1755251417000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":1,"title":["Performance of the bond capacity model for charge polarization in classical molecular dynamics"],"prefix":"10.1063","volume":"163","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7728-609X","authenticated-orcid":false,"given":"Elton","family":"Oyarzua","sequence":"first","affiliation":[{"name":"Department of Chemistry, Aarhus University , Langelandsgade 140, DK-8000 Aarhus,","place":["Denmark"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4576-5838","authenticated-orcid":false,"given":"Frank","family":"Jensen","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Aarhus University , Langelandsgade 140, DK-8000 Aarhus,","place":["Denmark"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"317","published-online":{"date-parts":[[2025,8,15]]},"reference":[{"key":"2025081505500813100_c1","doi-asserted-by":"publisher","first-page":"531","DOI":"10.1002\/med.20067","volume":"26","year":"2006","journal-title":"Med.
