Ir of methylene chloride. Vibrational model of methylene chloride. The above IR spectrum is for methylene chloride and there are many peaks which correspond to certain vibrations in methylene chloride. The peaks around 3100 1cm is due to the asymmetric stretching between the C-H atoms.

The large peak around 1250 1cm is due to the H-C-H out of plane wagging. The IR-spectrum can be divided into five ranges major ranges of interest for an organic chemist. From 2700-4000 cm-1 E-H-stretching.

EB 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. A common synonym for methylene chloride is dichloromethane.
