Abstract
We used high S/N, high spectral resolution observations to determine the isotope ratios 12C/13C and 14N/15N in comets. Observations were obtained with resolving powers R=λ/δλ ≫ 60,000 with telescopes at McDonald Observatory, VLT, NOT and Keck. We have now observed 13 comets on 20 different dates with heliocentric distances ranging from 0.6 au to 3.7 au. Most of these comets are from the Oort cloud; a few are members of the Jupiter family comets [2, 5, 4, 8, 6].
