25. A preliminary result obtained by DFT calculations suggests that two antiparallel (i.e., photocyclizable) conformations are particularly stable (more than 98% population at 25 °C), in which the two sets of N-H distances are around 0.26 nm, almost the same as the sum of van der Waals radii of N and H. Theoretical aspects of this problem will be reported separately.
