HN value is -68.6 Hz. The lower experimental magnitude (56.8 Hz) is consistent with a larger vibrationally averaged N-H separation, as zero-point motion carries the proton towards the O atom.

Interestingly, there is evidence of a fluxional process by which the NH proton may be transferred between the two nitrogens, perhaps via 7. As the sample of 6-(15N)2 is warmed above -80°C, the 15N peaks broaden to the point of invisibility, whereas the 1H resonance becomes more complicated between -80 and -40°C, and a triplet (J, 25.5 Hz)9a at higher temperatures. The changes in 1H spectra were modeled as a dynamic AA′X-A2X system (X, H, A, 15N, line-shape analysts giving Ea, 8 kcal mol-1 for the fluxional process.13c Similarly, the 31P signals for 6 (δ 60.7 and 51.9 ppm at -100°C8b) coalesced near -55°C
