The lecturer dealt first with the porphyrins, a group of compounds upon ... The latter also contains an additional ring structure, derived from β-keto propionic-acid, in place of the propionic ...

This study not only shows how low-frequency Raman shifts can detect OOP deformations in porphyrin molecules caused by environmental changes, but also provides a useful tool to understand how these ...

Most notably, iron porphyrins were found to easily form oxo ... obviously represented a minimum energy structure. McKeown and colleagues had shown that the solvent (mainly methanol) present ...
