We report results of polarized Raman scattering and photoluminescence studies of nitrogen-doped diamond. Experimental data demonstrates observation of an anomalous increase in the intensity of the inelastic light scattering by optical phonons and photoluminescence at room temperature by both zero-phonon lines: for the neutral nitrogen NV0 center at 575.468 nm and for the other negatively-charged nitrogen NV− center 637.874 nm as well as for their vibronic phonon side bands correspondingly distributed in a wide spectral range. The data enables observation of the strong in-coming resonance for nitrogen NV0 and out-going resonance for nitrogen NV− centers.

Keywords:
multiband resonant Raman light scattering by optical phonons, zero-phonon lines, in-coming resonance for NV0 centers, out-going resonances for NV− centers.
