Variations in the hydrogen-bond geometry: (a) distance H1dP⋯O2P, (b) distance N1P⋯O2P and (c) angle N1P—H1dP⋯O2P for product molecules during the photoreaction. For N1P⋯O2P standard uncertainties are in the range 0.005–0.04 Å and the change is 0.17 (4) Å, which indicates that it is statistically significant at the 3σ level, i.e. with 99.7% probability. |
