This java applet displays the wave functions of the rigid rotor (rigid rotator), which are the spherical harmonics. In the center of the applet, you will see the probability distribution of the particle's position. The color indicates the phase. At the bottom of the screen is a set of phasors showing the magnitude and phase of some of the possible states.

You may select a single state by picking one of the phasors at the bottom and double-clicking on it. Or, you may click on the phasor and drag its value to modify the magnitude and phase. In this way, you can create a combination of states.
