The ground-state radiative widths of nine levels below 10.2 MeV in ${}_{}{}^{15}{}_{}{}^{}\mathrm{N}$ were measured using resonance fluorescence. The results are compared with various theoretical predictions and are found to best agree with very recent unpublished calculations in which the full $1\hslash \omega$ configurational basis is included in constructing the wave functions of the ${}_{}{}^{15}{}_{}{}^{}\mathrm{N}$ levels.
