FTIR官能基周波数表

A searchable map of functional groups to their characteristic FTIR absorption wavenumbers — covering 99 functional groups. Unlike a static textbook chart, every entry here links through to the published literature behind it. Type to filter, then click any group for the full peak list and citations.
