Ushahidi wa sasa wa FTIR ni mdogo sana kuunga mkono utambulisho thabiti wa kiwanja. Ingawa ingizo la karibu zaidi la maktaba ni 1-Chloro-2-iodobenzene, ujasiri wa mechi haupo kabisa na hakuna ushahidi wa moja kwa moja au wa fasihi unaothibitisha mgawo huo. Bendi zilizozingatiwa takriban 1595, 1396, na 1032 cm-1 zinafasiriwa kwa usalama zaidi kuashiria nyenzo ya kikaboni yenye tabia inayowezekana ya kunukia na bendi ya eneo la alama za vidole inayoendana na miundo ya kunukia iliyobadilishwa au yenye C-O/C-X, lakini hazianzishi kipekee benzene iliyo na halojeni. Hitimisho linaloungwa mkono zaidi kikemia kwa hivyo ni nyenzo ya kikaboni ya kunukia iliyolinganishwa dhaifu, ikiwezekana kiwanja cha aina ya benzene iliyobadilishwa, badala ya dutu iliyothibitishwa yenye jina.
Hatua zinazofuata zilizopendekezwa: Recollect the FTIR spectrum over the full range with improved signal quality, especially below 1000 cm-1, where substituted aromatic and carbon-halogen bands are often more informative. Check whether additional bands are present near the aromatic C-H stretching region around 3000 cm-1 and the out-of-plane aromatic substitution region around 900-650 cm-1 to test the substituted benzene possibility. If available, confirm composition with GC-MS or LC-MS for a small-molecule sample, or complementary Raman spectroscopy if aromatic substitution pattern information is needed. If the sample is suspected to be halogenated, elemental screening such as XRF or MS isotope-pattern analysis would help verify the presence of Cl or I before accepting the library hit.
