Before going on to something as complex as an atom, let's look at a model problem in some detail. The first one is the one-dimensional particle-in-a-box problem. This turns out to be an excellent conceptual model for conjugated dye molecules (see Chapter 21) and also a model for ...

2. THE MODEL The left and right wall of a horizontally shaken con- tainer of length L are described by the equations x leftwall = Asin(ωt) x rightwall = L +Asin(ωt) . ω is the frequency, and A the amplitude of shaking. We denote position and velocity of the particle by x ...
In quantum mechanics, the particle in a box model (also known as the infinite potential well or the infinite square well) describes a particle, which is free to move in a space surrounded by impenetrable barriers. In classical systems, for example a ball trapped inside a heavy box, the ...

The results from a classic experiment in the undergraduate physical chemistry laboratory, the particle-in-a-box model for spectroscopic transitions of conjugated dyes, is compared to computational results obtained using a molecular mechanics structural approach and the extended H眉ckel molecular orbital ...
Variational studies employing the basis functions of the quantal particle-in-a-box model are shown to lead to accurate estimates of eigenvalues, various expectation values and eigenfunctions of the stationary anharmonic oscillator problem. Calculations involve both zx 2α and ( x 2+ zx 2α )-...
A connection between condensed matter physics and basic quantum mechanics is demonstrated as we use the fundamental 3D particle-in-a-box model to explain the optical properties of semiconductor nanocrystals, which are substantially modified due to quantum confinement. We also discuss recent advances in...
