Study on the ~1 H NMR Specra of Three 1.4-Dihydro nicotinamide coenzymes and Their Intermediates

The 1 HNMR specera of three 1.4 dihydro nicotinamide coenzymes and their intermediates were studied.The 1 H chemical shifts were gained and their regularity has been approached intialy.Their elemental analysis and IR spectra have been characterized,and the structure of these compounds in solution were characterized and determinatied,respectively.
