Spectrum of a section of the J = 1–0 rotational transition of LiCCCN near 5.2 GHz showing the multiple hyperfine components arising from both 7Li (I=3/2) and 14N (I=1) nuclei. The coaxial arrangement of the adiabatic expansion and the resonator axis produces an instrumental Doppler doubling. The resonances frequencies are calculated as the average of the two Doppler components. Each hyperfine component is labeled with the corresponding values of F1´, F´←F1´´, F´´ quantum numbers.
