In this study, some molecular properties of these molecules were determined theoretically, by using extended Hückel molecular orbital (EHMO or EHT) method and cycloaddition reactions of some norbornenyl-fused aromatic systems have been explained from EHMO data.eninfo:eu-repo/semantics/closedAccessAdduct; Bis-adduct; Extended Hückel molecular orbital theory (EHMO); Norbornenyl-fused aromatic systemsArticle237316531682-s2.0-79955542825Q4
