Abstract
A new series of compounds is proposed to serve as an experimental example of the one-dimensional particle in a box model. The compounds studied are: 1,4-diphenyl-1,3-butadiene, 1,6-diphenyl-1,3,5-hexatriene, and 1,8-diphenyl-1,3,5,7-octatetraene. In all three compounds the distance between the phenyl groups is taken as the length of the one-dimensional box. The lowest energy peak in the ultraviolet absorption spectrum corresponds to the lowest energy transition in the molecule and is used to determine the experimental length of the box. The experimental box length agrees well with the box length determined from average bond length data and the percent errors are similar to those obtained when a series of polymethine dyes are used to represent the box.

Bruce D. Anderson and Christopher M. GordonJournal of Chemical Education2008 85 (9), 1279In this experiment, linear polyynes are synthesized and then the predictions of a one-dimensional, particle in a box are used to calculate the quantum mechanical box length for the polyynes. A solution of graphite in ethanol is irradiated with a Nd:YAG ...

Why the Particle-in-a-Box Model Works Well for Cyanine Dyes but Not for Conjugated Polyenes
Jochen AutschbachJournal of Chemical Education2007 84 (11), 1840Why the Particle-in-a-Box Model Works Well for Cyanine Dyes but Not for Conjugated Polyenes
Jochen AutschbachJournal of Chemical Education2007 84 (11), 1840We investigate why the particle-in-a-box (PB) model works well for calculating the absorption wavelengths of cyanine dyes and why it does not work for conjugated polyenes. The PB model is immensely useful in the classroom, but owing to its highly ...

Paul F. Newhouse and K. C. McGillJournal of Chemical Education2004 81 (3), 424Particle in the box (PIB) solutions to the Schrödinger equations are not new to physical chemistry. Many have been developed to demonstrate complex quantum mechanical techniques in a simplified form. This article outlines two PIB solutions to the ...
