Inadequate unit selection for diffuse reflectance FT-IR spectra conceals low intensity bands of adsorbates

Abstract

Diffuse Reflectance FT-IR spectroscopy (DRIFTS) is a prominent tool to investigate adsorbates on catalyst surfaces. Low intensity bands of adsorbates are inappropriately squashed when using the Kubelka–Munk transformation, concealing the Pd–CO signal associated with Pd nanoparticles in the example reported here.
