Electron-rich molecules form an extremely large class of molecules, and the results of quantum mechanical studies from different laboratories indicate that qualitative valence-bond descriptions for many of these molecules are incomplete in so far as they usually omit "long-bond" Lewis structures from elementary descriptions of bonding. For example, the usual representation for the electronic structure of the ground-state for 03 involves resonance between the (+1 o and Until standard Lewis structures ~ ~ (-I . b:‘" ~d· . . . . , recently, any contribution to resonance of the "long-bond" (or spin-paired o •• / •• ,. . has been largely ignored. diradica~ Lewis structure However, it :0 . 0. . e-. . . . . ______ " has now been calculated to be a very important structure. For the ground-states of numerous other systems, calculations also indicate that "long-bond" structures are more important than is usually supposed, and therefore they should frequently be included in qualitative valence-bond des | | 出版日期 | Textbook 19821st edition | | 关键词 | Configuration Interaction; Organische Chemie; Planet; Theoretische Chemie; Valenzstrukturmethode; Walden | | 版次 | 1 | | doi | https://doi.org/10.1007/978-3-642-93216-8 | | isbn_ebook | 978-3-642-93216-8Series ISSN 0342-4901 Series E-ISSN 2192-6603 | | issn_series | 0342-4901 | | copyright | Springer-Verlag Berlin Heidelberg 1982 |
