## Homework Statement

I am trying to get the hamiltonain operator equality for a rigid rotor. But I don't get it. Please see the red text in the bottom for my direct problem. The rest is just the derivation I used from classical mechanics.

## Homework Equations

By using algebra we obtain:

By using this defintion K of rotational kinetic energy one writes:
