    You will measure the absorption spectra of a series of conjugated dyes and then use two theoretical models, the Particle-In-A-Box Approximation and, later, the Hückel Molecular Orbital Approximation to explain the observed spectra.


    The general approach to this experiment is adapted from D. P. Shoemaker, C. W. Garland, and J. W. Nibler, Experiments in Physical Chemistry, 6th edition, McGraw Hill Co. Inc, NY, 1996, p378. The experiment has been revised to suit our laboratory environment.
