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,
