Trifluoromethane (CHF 3 ) has been studied using 1 H, 13 C and 19 F NMR spectra in the gas phase at 300 K. For the first time all the spin-spin couplings and 13 C shielding of CHF 3 were measured as functions of density. After extrapolation to the zero-density limit the appropriate shielding ( 1 H,

## Abstract ^13^C, ^1^H spin coupling constants of dimethylacetylene have been determined by the complete analysis of the proton coupled ^13^C NMR spectrum. For the methyl carbon ^1^__J__(CH) = + 130.6~4~ Hz and ^4^__J__(CH) = + 1.5~8~ Hz, and for the acetylenic carbon ^2^__J__(CH) = − 10.34 Hz and
