[en] We report on high spectral resolution observations of the peculiar comet C/2016 R2 (Pan-STARRS). This comet was found to have a highly unusual composition, with a very high abundance of CO, and is only the third comet in which the N2+ ion is clearly detected. Our observations allowed us to measure the N2+/CO+/CO2+ ratios. Among other things, we also put an upper limit to the 14N/15N isotopic ratio, measured for the first time directly from N2+, and detected the [NI] lines for the first time in a comet.
