2. Raman and XPS spectroscopic analysis also established the existence of sp-hybridised intermediate. The N=N stretch vibrational mode in the Raman spectra at 1442cm-1 in trans-azo upshifted to 1453 cm-1 in the cocrystal.

Double racemic cocrystal generated by induction of twist from octabrominated perylene diimide host to achiral azobenzene guest through noncovalent interactions.

Azobenzene follows rotation and inversion pathways during photoisomerization. Inversion mechanism requires one of the nitrogen atoms to transition via sp hybridized state. N=N bond distance of skewed azo in OBPDI-AZO1 was lower than trans-azo indicating a transition to sp state.
