WebIn IR or Raman spectra, a blue shift in a bond frequency corresponds to an increase in frequency or shift to higher wavenumbers. A red shift indicates a decrease in frequency or shift to lower wavenumbers. Here's an example: the frequency of the symmetric stretch in water is red shifted by 1000 wavenumbers following deuterium exchange. 3.
