Find the energy spectra of an axial-symmetric rotor
(1). If the rotor is in a stationary state, what are the possible
values that can be obtained by measuring "L_z" and what are its
probabilities?
Homework Answers
Thus the Schrodinger's equations
has the following solutions for energy
Recall that the angular part solution in a spherically symmetric solution satisfies the above Schrodinger equation. They simultaneous eigenvectors of L2 operator and Lz .
l can be 0, 1, 2,...and -l<=m<=l For each l, 2l+1 values are possible for m.
Since it is a stationary state the Lz measurement gives the
definite value of
