Rotation operator (quantum mechanics)

This article concerns the rotation operator, as it appears in quantum mechanics.
==Quantum mechanical rotations==
With every physical rotation R, we postulate a quantum mechanical rotation operator D(R) which rotates quantum mechanical states.
:| \alpha \rangle_R = D(R) |\alpha \rangle
In terms of the generators of rotation,
:D (\mathbf,\phi) = \exp \left( -i \phi \frac \right)
\mathbf is rotation axis, and \mathbf is angular momentum.
