Overhead Projector Spectrum of Polymethine Dye: A Physical Chemistry Demonstration

August 1995
Vol. 72 No. 8
p. 730
Abstract
The position of the predominant peak of 1,1'-diethyl-4,4'-cyanine iodide is measured in class using an overhead projector spectrometer, then predicted using the model of a particle-in a one dimensional box. The calculated wavelength is in excellent agreement with the wavelength estimated from the overhead projector spectroscopy experiment.
