Homework Help: Rigid Rotor question requiring quantum mechanics.

  1. Feb 25, 2012 #1
    1. The problem statement, all variables and given/known data

    A rigid rotor with moment of Inertia I is known to be in a state with eigenfunction Y3,-2(θ,∅).

    A. What is the rotational energy of the rotor in terms of I and h bar.
    B. What is the uncertainty in the measurement of the energy of the rotor?

    2. Relevant equations

    Y3,-2(θ,∅) = (105/32∏)^(1/2)sin^2(θ)cos(θ)e^-i2∅.

    3. The attempt at a solution

    All i have figured out from the notes is that for a rigid rotor E = 0.5ω2 and delta E = <E^2>-<E>^2 however i cannot apply it here.
