What absorbs at 438 cm⁻¹ in an FTIR spectrum?
Et bånd nær 438 cm⁻¹ kan peke på flere funksjonelle grupper. Nedenfor er de mest sannsynlige tildelingene, rangert etter hvor mye publiserte bevis som støtter hver — hver enkelt sporbar til litteratur (DOI) og kryssvalidert mot våre 130 000+ referansespektre og kunnskapsgraf.
