Webbvibrate which can affect the band shapes. Two common perturbations in IR and Raman are hot bands and isotope effects. Overtones and combination bands can also occur, and other relaxation pathways exist (resonance transfer, Fermi resonance, etc.), all of which alter peak locations and widths – see the literature for more information.
