AB  - MoS<sub>2</sub> has recently emerged as a promising material for enabling quantum devices and spintronic applications. In this context, an improved physical understanding of the g-factor of MoS<sub>2</sub> depending on device geometry is of great importance. Resistively detected electron spin resonance (RD-ESR) could be employed to determine the g-factor in micron-scale devices. However, its application and RD-ESR studies have been limited by Schottky or high-resistance contacts to MoS<sub>2</sub>. Here, we exploit naturally n-doped few-layer MoS<sub>2</sub> devices with ohmic tin (Sn) contacts that allow the electrical study of spin phenomena. Resonant excitation of electron spins and resistive detection is a possible path to exploit the spin effects in MoS<sub>2</sub> devices. Using RD-ESR, we determine the g-factor of few-layer MoS<sub>2</sub> to be ∼1.92 and observe that the g-factor value is independent of the charge carrier density within the limits of our measurements.
