Subject: Physical Chemistry · Chapter: Quantum Chemistry · Topic: Angular Momentum · Exam: NET JUNE 2014 · Marks: 2 · Difficulty: Medium

The angular momentum operator $\mathrm{L}_{\mathrm{z}}=-\mathrm{i} \hbar \frac{\partial}{\partial \phi}$ has eigen functions of the form $\exp (\mathrm{iA} \phi)$. The condition that a full rotation leaves such an eigen function unchanged is satisfies for all the values of A

(a)$0, \pm \frac{1}{3}, \pm \frac{2}{3}, \pm 1, \pm \frac{4}{3}$

(b)$0, \pm 1, \pm 2, \pm 3, \pm 4$

(c)$0, \pm \frac{}{2}, \pm 1, \pm \frac{-}{2}$

(d)$0, \frac{-}{2}, \frac{-}{2}, \frac{1}{2}, \frac{1}{2}$
