What absorbs at 2002 cm⁻¹ in an FTIR spectrum?
A band near 2002 cm⁻¹ can point to several functional groups. Below are the most likely assignments, ranked by how much published evidence supports each — every one traceable to literature (DOI) and cross-validated against our 130,000+ reference spectra and knowledge graph.
