Synthesis and Characterization of New Schiffs Bases Derived from D-Erythroascorbic Acid and Pyrimidines	2017	16	.pdf	application/pdf	4279	274	75	The structure of the oxopyrimidine [VI]a-d characteristic by FTIR spectra which are showed the disappearance of two absorption bands of new absorption bands for NH,C=O (amid) and C=N (endocyclic at ( 3433) cm -1 , (1639) cm -1 and (1610) cm -1 , respectively. The FTIR spectrum showed a broad stretching band at (3240-3074) cm-1 for(O-H) vinylic, stretching bands at (2993-2908) cm-1 for (C-H) aliphatic, acetal linkage stretching band at(1755) cm-1 due to (C=O) of Lactone ring , stretching band at(1685) cm-1 for (C=C) and stretching bands at (1141-900) cm-1 for C-O stretching .	cache/iajs-768.pdf	txt/iajs-768.txt
