We have measured the spin splitting in single-layer and bilayer graphene by means of tilted
magnetic-field experiments. By applying the Lifshitz-Kosevich formula for the spin-induced
decrease of the Shubnikov-de Haas amplitudes with increasing tilt angle, we directly
determine the product between the carrier cyclotron mass m* and the effective g factor g* as
a function of the charge-carrier concentration. By using the cyclotron mass for a single-layer
and a bilayer graphene, we find an enhanced g factor g*= 2.7±0.2 for both systems.
