The solid-state formation of a centrosymmetric cage dimeric 4-aryl-1,4-dihydropyridine was monitored by 13 C cross polarization magic angle spinning (CP/MAS) NMR spectroscopy. The spectra of the photodimerizing derivatives document the changes in symmetry during the reaction and the reaction progres
