We model the decoherence and dephasing of nitrogen vacancy (NV) centers in\ndiamond due to a noisy paramagnetic bath, with and without the presence of a rf\nfield that couples levels of the ground electronic state manifold, using a\nsimple quantum mechanical model that allows for analytical solutions. The model\ntreats the NV three-level ground state system in the presence of fluctuating\nmagnetic fields that arise from the environment, and that result in\ndecoherence, dephasing and dissipation. We show that all 9 eigenmodes of the\nthree-level system are coupled to each other due to interaction with the\nenvironment, and we discuss consequences for fitting experiments in which\ndecoherence plays a role.\n
