Polarography of 5,5'-dithio bis-(2 nitrobenzoic acid) in the pH range 2-12, in Britton-Robinson buffer at constant ionic strength (0 .5 M) has been carried out. Four cathodic waves (A, B, C and D) and an anodic wave have been obtained . Wave A is produced by a reduction of pre-protonated nitro group
The IR and Raman spectra of polycrystalline anhydrous orotic acid and its N1, N3, and O12 trideuterated isotopomer are recorded in the 4000 -40 cm Οͺ1 spectral interval as part of a series of vibrational analyses of nucleosides, nucleotides, and related compounds carried out in our laboratory.
