WebApr 1, 2002 · The IR-spectrum can be divided into five ranges major ranges of interest for an organic chemist: a. From 2700-4000 cm-1 (E-H-stretching: E=B, C, N, O) In this range typically E-H-stretching modes are observed. The C-H-stretching modes can be found between 2850 and 3300 cm-1, depending on the hydrization.
