Variations in (a) the C9⋯C10i distance between directly reacting atoms [(i) -x, 1-y, 1-z], (b) the C9—C16—C15i and (c) the C10—C15—C16i valence angles with the photoproduct content in the crystals. Standard uncertainties for the distance and for the valence angles are in the ranges 0.002–0.03 Å, 0.13–0.8 and 0.13–0.7°, respectively. |
