Juárez López, Gabriela Sanz Novo, Miguel Aguado Vesperinas, Raúl Alonso Hernández, José Luis León Ona, Iker Alonso Alonso, Elena Rita 2023 Producción Científica This work reports a complete conformational analysis of caffeic acid, an exceptionally versatile pharmacophore, using laser ablation chirped-pulse Fourier transform microwave spectroscopy. The whole conformational space consisting of eight distinct species has been fully deciphered based on the trend of the rotational constants supported by theoretical computations. We show how rotational spectroscopy can be confidently used to distinguish between conformers even when the structural differences are minimal, such as those involved in the conformational panorama of caffeic acid. Additionally, the structural information here provided, such as the planarity observed in all the conformers, could help to elucidate the mechanisms underlying the biological and pharmacological activity of hydroxycinnamic acids. application/pdf https://uvadoc.uva.es/handle/10324/81564 eng Royal Society of Chemistry 23 Química 2210 Química Física 2206.07 Espectroscopia Molecular The eight structures of caffeic acid: a jet-cooled laser ablated rotational study info:eu-repo/semantics/article TEXT UVaDOC.
