Abstract
Die Lage des Maximums der ersten (im Sichtbaren liegenden) Absorptionsbande von symmetrischen Cyaninfarbstoffen wird ermittelt unter Zugrundelegung eines Modells der Farbstoffmolekel, welches analog ist zu dem insbesondere von Sommerfeld als Modell für das Metall verwendeten Bild des freien Elektronengases. Die π‐Elektronengas der Polymethinkette werden als eindimensionales, freies Elektronengas betrachtet, welches sich der Polymethinkette entlang hinzieht.Keywords
