Die Newman-Projektion eignet sich zur Darstellung der Konformation eines Moleküls. Man unterscheidet bei Alkanen verschiedene Konformere, auch Rotamere, anhand ihres Torsionswinkel. Sie eignet sich ebenfalls zur Beschreibung von Reaktionsmechanismen und der Vorhersage der Stereochemie eines Reaktionsproduktes, beispielsweise nach der Cramschen Regel. Keilstrichformeln können in die Newman-Projektion überführt werden, indem man das Molekül „… WebConformations can be described by dihedral angles, which are used to determine the placements of atoms and their distance from one another and can be visualized by …

WebOrganic Chemistry Newman Projections When atoms in organic molecules connect via single bonds, you can have a free rotation around those single bonds. That gives you a different 3D forms of the same molecule. We refer to those forms as conformations of the molecules. These molecular conformations may be somewhat challenging to represent. … http://www.coosmeester.nl/MANP/Klinische%20besluitvorming/01%20coos%20neuman%20samenvatting.pdf Web1 apr. 2024 · Noun [ edit] conformation ( countable and uncountable, plural conformations ) The act of conforming; the act of producing conformity.
