Transient states in [2 + 2] photodimerization of cinnamic acid: Correlation of solid-state NMR and X-ray analysis

Article abstract of DOI:10.1021/ja0773711

¹³C-CPMAS and other solid-state NMR methods have been applied to monitor the solid-state reactions of trans-cinnamic acid derivatives, which are the pioneer and model compounds in the field of topochemistry previously studied by X-ray diffracti
