A method for precise characterization of wavelengths for spontaneous and stimulated emission of molecules XeCl 3030-3100 {\AA} (transition $B^{2}Σ _{1 / 2}^{ +} \to X^{2}Σ _{1 / 2}^{ +} )$ is described. The region of the emission spectrum for iron hollow cathode lamp in this spectral range is shown. Reciprocal linear dispersion of the spectrograph is 0.53 {\AA}/mm. This method allows accuracy of wavelength characterization better than 0,003 {\AA}. Wavelength for 131 identified lines are characterized, including lines for other elements (atoms and ions of Ne, Ni, Al, Co), which are present in this spectrum. Wavelength for emission spectrum for XeCl laser with electric discharge excitation are characterized for electron-oscillation transitions 0-0, 0-1, 0-2, and 0-3. The obtained emission spectrum for hollow iron cathode lamp could be applied as the atlas for the spectral range 3030-3100 {\AA}.
