What absorbs at 488 cm⁻¹ in an FTIR spectrum?
Et bånd nær 488 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.
Backed by 7 cited sources
Mulige funksjonelle gruppe-tilordninger
| Funksjonell gruppe | Støttende fakta | Siterte kilder | Toppkonfidens |
|---|---|---|---|
| Metal oxygen | 2 | 2 | 1.0 |
