## Abstract The three structural isomers bilirubin IXฮฑ (**1a**), IIIฮฑ (**2a**), and XIIIฮฑ (**3a**) have been separated on a preparative scale by highโperformance lowโpressure liquid chromatography. They were converted into their dimethyl esters **1b, 2b**, and **3b** and characterized by UV, IR, MS

## Abstract Reverse phase high performance liquid chromatography (HPLC) was used to separate and quantify aromatic diesterโdiacids isomers which arise from the opening selectivity of anhydride rings towards methanol. ^13^C NMR spectroscopy was a supplementary tool to characterize the isomer structu
The structural characterization of the E and 2 isomers of p-nitrophenyl-diazo tert-butyl sulphide has been achieved by means of different ionization methods (electron impact, fast atom bombardment, positive-ion chemical ionization) and collision experiments performed under different kinetic energy r
