Facile Structural Elucidation of Glycans Using NMR Spectroscopy Data and the Program CASPER: Application to the O‐Antigen Polysaccharide of Escherichia coli O155

Time saver: The program CASPER was successfully employed to rapidly elucidate a new O-antigen polysaccharide structure (obtained from a strain of Escherichia coli serogroup O155), using solely unassigned NMR spectroscopy data as input information. Thus, what is considered the most tedious and time-consuming part of the structural elucidation process has been reduced from several hours (or even days) of manual interpretation to about four minutes of automated analysis.
