    • 3. The structure contains a single crystallographic type of antiparallel, anti molecules of 3-HOBDI stacked at 3.64 Å. Unlike 3-HOBDI -B and 3-HOBDI -C, the molecules do not form dimers; instead, they are monomeric and are connected into pairs by two C-HO hydrogen bonds between the carbonyl group and one of the methyl groups.

    • In retrospect, we now recognize that several of these derivatives showed the presence of "impurities" in purified samples, a phenomenon we can now attribute to the photodimerization and which serves as a caution when handling such compounds in the solid state

    • All atoms except for C3' of the imidazolone ring of the product molecule (primed in Figure 7) were clearly observed in the difference map. The secondary component of the ipso -carbon (C3') could not be observed as sufficiently high separate residual density, probably due to its close proximity with the same atom (C3) of the reactant. Within the molecule, residual peaks of only the imidazolone ring and the bridging C-atom were observed, showing that the molecular isomerization occurs only on the imidazolone half of the molecule; the position of the phenyl ring did not change during the reaction, and therefore, it was refined as a single component
