In this study, we extend a previously applied analysis based on the algebraic diagrammatic construction scheme for electronic excitations (ADC) framework to a broader family of heteroacenes, including aza-, phospha-, and halogen-substituted anthracenes. Decomposition of the ADC diagonal elements and the corresponding perturbative effects from ADC(2) \u2192 ADC(1) \u2192 ADC(0) reveals orbital energy differences as the primary driver of excited state mixing and thus of the resulting oscillator strengths. This uncovers how substituent type and position shapes spectral intensities of the low-lying \u03c0\u03c0* electronic transitions, namely, 1Ls (1Lb) and 1Bb. Tip substitution consistently enhances the orbital energy difference and leads to bright \u03b1-bands (1Ls\/1Lb), whereas side substitution produces more symmetric mixing of configurations and weak \u03b1-bands. Across halogen series, increasing electronegativity while keeping the position unchanged generally leads to higher oscillator strength of the 1Ls (1Lb) state. These results provide a unified, general rule for tuning the spectral properties by substitution and\/or heteroatom replacement.<\/jats:p>","DOI":"10.1021\/acsphyschemau.6c00105","type":"journal-article","created":{"date-parts":[[2026,9,14]],"date-time":"2026-09-14T10:01:29Z","timestamp":1789380089000},"page":"1340-1348","source":"Crossref","is-referenced-by-count":0,"title":["Tuning Spectral\nProperties of Anthracenes through\nSubstitution"],"prefix":"10.1021","volume":"6","author":[{"given":"Vyshna","family":"Ratheesh","sequence":"first","affiliation":[{"name":"Ruprecht-Karls University , , Im Neuenheimer Feld 205 , ,","place":["Heidelberg, Germany, 69120"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-1941-4051","authenticated-orcid":true,"given":"Anna M.","family":"Weidlich","sequence":"additional","affiliation":[{"name":"Ruprecht-Karls University , , Im Neuenheimer Feld 205 , ,","place":["Heidelberg, Germany, 69120"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5862-5113","authenticated-orcid":true,"given":"Andreas","family":"Dreuw","sequence":"additional","affiliation":[{"name":"Ruprecht-Karls University , , Im Neuenheimer Feld 205 , ,","place":["Heidelberg, Germany, 69120"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"316","published-online":{"date-parts":[[2026,9,14]]},"reference":[{"key":"2026092310064694000_cit1","volume-title":"Polycyclic Hydrocarbons","author":"Clar","year":"1964"},{"key":"2026092310064694000_cit2","doi-asserted-by":"publisher","first-page":"3193","DOI":"10.1002\/chem.202003112","article-title":"Pushing\nthe Limits of Acene Chemistry: The Recent Surge\nof Large Acenes","volume":"27","author":"To\u0308nshoff","year":"2021","journal-title":"Chem. - Eur.
