Search Strategies for IR Spectra - Searching ATR Spectra Against Transmission Data

Attenuated  Total  Reflectance  (ATR)  spectroscopy  is  used  in many  facilities  for  analyzing  various  materials.  A  spectrum collected  using  this  technique  can  differ  from  a  spectrum collected  using  a  transmission  technique,  particularly  in  the relative intensities of the bands. Most commercially available databases  and  proprietary  databases  have  been  collected using transmission techniques. This difference in technique, if not accounted for, can present difficulties when trying to search commercial or proprietary databases.
