Energy diagram of ground singlet-triplet levels 3A2 of NV in magnetic field up to 300 mT. “Forbidden” Δms = 2 and LF allowed Δms = 1 transitions caused by absorption of microwave radiation (ν ≈ 9.44 GHz) are marked by vertical red arrows. The position of the ground state spin level anti-crossing (|0 〉GS and |−1〉GS) is marked by a circle
