Notes:
The decomposition of 15N3F at -20°C leads to cis- and trans-15N2F2. The corresponding 19F NMR spectra were analysed as [AX]2 systems. 19F, 15N and 14N NMR spectra were simulated using the novel PC program systems DSYMPCD, DCYMPCD and WIN-DAISY running under WIN-NMR. Stereospecific coupling constants were obtained for both isomers. Comparison of the 19F NMR spectra from both the [1/2A1/2X]2 and the [1A1/2X]2 systems in 15N2F2 and 14N2F2 overcomes the inherent ambiguities of the [AX]2 analysis.
