Abstract: | Isotopic ratios in comets provide keys for the understanding of the origin of cometary material, and the physical and chemical
conditions in the early Solar Nebula. We review here measurements acquired on the D/H, 12C/13C, 16O/18O, 14N/15N, 32S/34S ratios in dust and gases, and discuss their cosmogonic implications. The prospects for future measurements from cometary
space missions and remote sensing observations at millimeter and submillimeter wavelengths are presented.
