... The diatomic molecule comprises two atoms, numbered 1 and 2, with respective atomic masses m1 and m2, a distance r apart. The center of mass (which is at a distance r1 from atom 1 and r2 from atom 2, such that r1+r2 = r) is located by recognizing that the moments of the masses should be equal around ...

... Now, we could proceed to work out the relationships for ⎡⎣ L̂ y , L̂z ⎤⎦ and ⎡⎣ L̂z , L̂ x ⎤⎦ . However, we note that our answer must always be invariant to a cyclic permutation x → y, y → z, z → x . This must be the case because our labeling of the x, y and z axes is totally arbitrary: if we chose ...
