N h — FTIR absorption peaks and assignments
These are the characteristic FTIR wavenumbers where N h tends to absorb, compiled from published literature and ranked by supporting evidence. Each assignment is traceable to a source (DOI) and cross-validated against our 130,000+ reference spectra and knowledge graph.
