WebInfrared spectroscopy (IR) is a tool that allows identification of the formation of hydrogen bond interactions, by the shift of the bands of the functional groups involved in the formation of the hydrogen bonds in the infrared spectra. In the IR spectra of LID-PLG(CH 2 Cl 2), the phenolic hydroxyl (O–H) and the amide carbonyl (C=O) bands were ...

WebIt is also important to understand that in order for a bond to absorb IR light, there must be a change in the bond’s dipole moment during the molecular vibration. For example, 2,3-dimethyl-2-butene has an IR inactive C=C bond stretch due to molecular symmetry. During the C=C bond stretch there is no change in the bond’s dipole moment. RCCR ...
