    "abstract": "Velocity-modulation Fourier transform emission spectra from a N_2O/He\ndischarge plasma recorded between 1 and 5.5 $\\mu$m are described. Surprisingly,\nthey show Doppler-shifted lines for the E ^2 \\Sigma ^+ - D ^2 \\Sigma ^+, C ^2\n\\Pi - A ^2 \\Sigma ^+, and D ^2 \\Sigma ^+ - A ^2 \\Sigma ^+ Rydberg-Rydberg\nrovibronic transitions of the nitric oxide neutral molecule. These\npolarity-dependent Doppler-shifts are those of positively charged particles.\nVibration-rotation lines of NO and transitions from other neutral molecules\nlike N_2 are also present in the spectra with comparable intensities and remain\nunshifted. Experimental investigations and possible explanations are discussed.",
