Copropagating-beam Doppler-free resonances, observed in fluorescence, are utilized to study vibrational dependence of N2O quadrupole hyperfine structure for several transitions of the (100–001) band. A novel technique is applied to simplify the spectra by using a large intensity ratio for the beams.
