My experience is that ATR correction should particularly be used when acquiring spectra for compounds that contain OH or NH groups as the absorbances for these functional groups will be very low without these corrections.
For FTIR analysis, accessories can be categorized as ATR, Diffuse Reflection, Specular Reflection, and Transmission. Visit our application section of our website where we have posted short summaries of each method. You’ll find these under each header.
