Assignments are provided for the protons and directly bonded carbons of 3‐ and 8‐episirohydrochlorin methyl esters based upon material isolated from Desulfovibrio vulgaris . The chemical shifts of the two isomers are highly similar to each other and also to the physiologically relevant authentic sirohydrochlorin, but are sufficiently distinct that NMR can be reliably used to detect their presence in natural isolates. © 1997 by John Wiley & Sons, Ltd.
