See Answer. environments. If these two spectra are compared, in the case of DGEVA/DDM system, a broad band centered at 3370 cm 1 is detected, attributed to the alcohol groups formed after the reaction of the epoxy groups of DGEVA and the amine . General Spectroscopy and Dynamics. The interactive spectrum display requires a browser with JavaScript and Since most organic compounds have C-H bonds, a useful rule is that absorption in the 2850 to 3000 cm-1 is due to sp3 C-H stretching; whereas, absorption above 3000 cm-1 is from sp2 C-H stretching or sp C-H stretching if it is near 3300 cm-1. alkenes, arenes, alcohols, amines & carbonyl compounds) may be viewed by clicking on the functional class name. 1 1 !
