This single line together with rocket observations of the CO ultraviolet bands (Smith and Stecher, 1969) has provided our total knowledge of the relative abundance of

Except for the Orion Molecular Cloud, all H.CO ratios were obtained from the 1.-1. absorption line, at 4.8 GHz. The HC.N data of Churchwell et al. ((1976), ref. 7 in Table 1) were measured at 9 GHz. All other isotope results were obtai

The .c/.c ratio for the carbon in the gas is then raised by factors ～ 2 to 4. Fractionation of deuterium is also discussed since the proposed process is similar to the carbon isotope excha

Study of isotopes is indeed most profitable in the sense that they are less affected than elements by chemical fractionation processes although such processes can be considered and be important (see e.g.
