What are the Types of IR Spectroscopy?

Several types of IR spectroscopy are commonly used in catalysis research:
Transmission IR Spectroscopy: Measures the absorption of IR radiation as it passes through a sample.
Diffuse Reflectance Infrared Fourier Transform Spectroscopy (DRIFTS): Suitable for studying powders and heterogeneous catalysts, where IR radiation is scattered and reflected from the sample.
Attenuated Total Reflectance (ATR) Spectroscopy: Ideal for studying surface phenomena, as it measures the absorption of IR radiation by a thin layer of the sample in contact with an IR-transparent crystal.
