We present high-resolution optically detected magnetic resonance (ODMR)spectroscopy on single nitrogen-vacancy (NV) center spins in diamond at andaround zero magnetic field. The experimentally observed transitions dependsensitively on the interplay between the microwave (MW) probing field and thelocal intrinsic effective field comprising strain and electric fields, whichact on the NV spin. Based on a theoretical model of the magnetic dipoletransitions and the MW driving field, we extract both the strength and thedirection of the transverse component of the effective field. Our resultsreveal that for the diamond crystal under study, strain is the dominantcontribution to the effective field. Our experiments further yield a method forMW polarization analysis in a tunable, linear basis, which we demonstrate on asingle NV spin. Our results are of importance to low-field quantum sensingapplications using NV spins and form a relevant addition to the ever-growingtoolset of spin-based quantum sensing.
