Angular Momentum 23.1 Classical Description
... We learn that, for example, [L̂x , L̂y ] = i ~ Lz . This tells us that it is impossible to find eigenfunctions of Lx that are simultaneously eigenfunctions of Ly and/or Lz . So returning to the issue of [Ĥ, L̂i ] = 0, we can, evidently, choose any one of the angular momentum operators, and have sha ...

... The equations (4.12), (4.13) and (4.16) now allow us to construct a 3-dimensional depiction of the wave functions for n = 1, 2 and 3. Let’s begin with the spherical s-orbitals. 1s has no radial zero points, 2s has one, and 3s has two. We will depict a cross-section of the orbitals (for example z = 0 ...
