Qualitative surface characterization of Indian Permian coal using XPS and FTIR

Enhanced electrochemical determination of quercetin in a choline chloride-based ionic liquid

“…The intensities and areas of the peaks are used to quantify functional groups. 43–45 The DES treatment influenced the absorption band of quercetin functional groups. The height of peaks at 3290 cm −1 corresponding to H-bonded phenols and alcoholic group vibrations was reduced.…”
