Synthesis and antimicrobial evaluation of new 1,3,4 – Thiadiazole Derivatives	2017	9	.pdf	application/pdf	2628	177	76	The IR spectra which showed stretching bands at (1670 – 1680 cm-1) of ( C = O amide ) ( 1610 – 1620 cm-1 ) of ( C = N ) and (3116 , 3031 cm -1 ) of ( C – H aromatic ) of the benzene ring for compound [ VII a ] , compound [ VII b ] gave diagnostic IR stretching bands at ( 1255 cm-1 ) of ( C = S ), (1600 -1610) of (C=N) and ( 3110,3025 cm-1) of (C-H) aromatic of the benzene ring . [IIa-c] , the IR spectra of Schiff bases showed the stretching bands at ( 1670 – 1675) cm-1 for ( C = N ) groups and disappeared at ( 3450 – 3300 cm-1) , ( 3290 – 3250 cm-1) due to ( NH2 ) .	cache/iajs-395.pdf	txt/iajs-395.txt
