  We study the forced rotation of Titan seen as a rigid body at the equilibrium
Cassini state, involving the spin-orbit synchronization. We used both the
analytical and the numerical ways. We analytically determined the equilibrium
positions and the frequencies of the 3 free librations around it, while a
numerical integration associated to frequency analysis gave us a more
synthetic, complete theory, where the free solution split from the forced one.
We find a mean obliquity of 2.2 arcmin and the fundamental frequencies of the
free librations of about 2.0977, 167.4883, and 306.3360 years. Moreover, we
bring out the main role played by Titan's inclination on its rotation, and we
suspect a likely resonance involving Titan's wobble.
