Abstract
The 13CCH and C 13CH submillimetre wave spectra have been observed inside a R.F. glow discharge in a mixture of 13CO, CH4, and He. Accurate molecular constants have been derived, and the frequencies of the lines of astrophysical interest have been predicted. Using previously published data on CCH and CCD, a substitution structure has been determined and compared with ab initio calculations.Keywords
