The experimental measurements were performed using the relative flow method with helium as the standard gas in a crossed electron\u2013molecular beam arrangement. The measurements cover incident electron energies from 0.7 to 30\u00a0eV and scattering angles between 10\u00b0 and 130\u00b0. The experimental DCSs are compared with Schwinger multichannel calculations employing pseudopotentials within the static-exchange plus polarization (SEP) approximation for electron-impact energies up to 30\u00a0eV. Owing to the large permanent dipole moment of acrylonitrile, the Born-closure procedure was applied to account for the long-range dipole interaction. The large dipole moment also suggests the possible existence of a dipole-bound state, in which the excess electron occupies a highly diffuse orbital localized in the positive region of the molecular electrostatic dipole potential. To place the acrylonitrile results in the context of the nitrile series, we compare them with previously published experimental data for hydrogen cyanide (formonitrile, HCN) [S. K. Srivastava, H. Tanaka, and A. Chutjian, J. Chem. Phys. 69, 1493 (1978)] and acetonitrile (CH3CN) [M. Zawadzki and M. A. Khakoo, J. Chem. Phys. 149, 124304 (2018)]. The comparison indicates that, while the strong forward scattering is primarily governed by the permanent dipole moment, acrylonitrile exhibits enhanced scattering at larger scattering angles (\u03b8 &amp;gt; 80\u00b0), which may be associated with low-lying \u03c0* resonances facilitated by its extended \u03c0-conjugated structure.<\/jats:p>","DOI":"10.1063\/5.0345253","type":"journal-article","created":{"date-parts":[[2026,9,30]],"date-time":"2026-09-30T10:35:53Z","timestamp":1790764553000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":0,"title":["Experimental and theoretical study of low energy differential elastic electron scattering from acrylonitrile (C2H3CN)"],"prefix":"10.1063","volume":"165","author":[{"ORCID":"https:\/\/orcid.org\/0009-0004-0777-4516","authenticated-orcid":false,"given":"W.","family":"Bregu\u0142a","sequence":"first","affiliation":[{"name":"Department of Physics of Electronic Phenomena, Faculty of Applied Physics and Mathematics, Institute of Physics and Applied Computer Science, Gda\u0144sk University of Technology 1 , ul.
