The synthetic spectrum of CN isotope violet bands is computed: it appears that several lines of 13CN and C15N are potentially detectable in spectra obtained with a spectral resolution of 0.1 Å or better. The fluorescence efficiencies of those lines is given as a function of both the radial velocity and the heliocentric distance of the comet. The Swings effect is shown to enhance the intensity of the isotope lines relative to that of the most common lines at specific radial velocities and hence to favour their observation.
