The O-specific polysaccharide of Proteus penneri O16 was studied by 1H and 13C NMR spectroscopy, including 2D COSY, TOCSY, NOESY and H-detected 1H,13C HMQC, HMQC-TOCSY and 1H,31P HMQC experiments, along with chemical methods. The polysaccharide was found to be a ribitol teichoic acid-like polymer having the following structure:
