Notizen:
Carbon-13 spin-lattice relaxation times (T1) and 13C-{19F} nuclear Overhauser enhancement (NOE) factors have been measured for some simple fluorocarbons by pulse-Fourier transform methods - ‘progressive saturation’ and ‘dynamic Overhauser enhancement’. The NOE factors are shown to be large for 13C with directly bonded fluorines, and the values for T1 and the NOE factors are similar to those obtained elsewhere on the corresponding hydrocarbons.
