What are the Limitations of Transmission IR in Catalysis?
Despite its advantages, Transmission IR also has some limitations: 1. Sample Preparation: The technique often requires thin and uniform samples to ensure accurate measurements, which can be challenging to prepare. 2. Interference: The presence of strong IR absorbers like water can interfere with the spectra, complicating the analysis. 3. Surface Sensitivity: While Transmission IR is effective for bulk analysis, it may be less sensitive to surface species compared to techniques like Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS).
