To describe experiments on fluorescence excitation of single N-V defect centers in diamond we have used the double well potential (DWP) model which incorporates the possibility of tunneling the nitrogen atom into the vacancy both in ground and excited electronic states of the center. Fluorescence and linear absorption spectra are calculated, DWP's parameter values for N-V centers are determined and manifestations of their variations due to local diamond lattice distortions in fluorescence spectra of various single N-V centers are studied.

Abstract The theory of interwell and intrawell relaxation is developed. Numerical calculation of appropriate transition propabilities is realized. It shows relaxation dependence on temperature and two‐well system parameters. On the basis of the same theory two specific experimental effects (the appearance of “multiplets” in quasi‐line spectra and “hole‐burning”) are analyzed.
