Additional terms and conditions may apply. Please see product information on the Sigma-Aldrich website at www.sigmaaldrich.com and/or on the reverse.. In IR spectroscopy, an organic molecule is exposed to infrared radiation. When the radiant energy matches the energy of a specic molecular vibra-tion, absorption occurs. To facilitate this analysis, compilations of IR spectra are available, most well-known of which are those by Sadtler and Aldrich In IR spectroscopy we measure where molecules absorb photons of IR radiation. The peaks represent areas of the spectrum where specific bond vibrations occur. [for more background, see the previous post, especially on the ball and spring model]. Just like springs of varying weights vibrate at..
