The moon undergoes synchronous rotation, and as a consequence the: rotational period of the Moon is equal to the orbital period of the Moon around the Earth.

Synchronous rotation is the rotation of a celestial body in which the rotational period is equivalent to the period of orbit around the body it is orbiting, leaving the same face constantly pointing toward the body it is orbiting. The earth's moon demonstrates synchronous rotation.
