Ushahidi wa kawaida wa FTIR unaunga mkono nyenzo kikaboni yenye kabonili alifatiki, na mkato wa juu zaidi kuwa kiwanja kama ketoni na pengine ketoni ya mzunguko. Kidokezo cha juu cha maktaba ni Cycloheptanone, lakini nguvu ya mechi haipo na hakuna ushahidi wa marejeleo ya moja kwa moja au fasihi inayohusiana unaothibitisha kwa uhuru mgawo huo mahususi. Bendi iliyozingatiwa ya 1699 cm-1 inalingana na unyonyaji wa C=O wa aina ya ketoni, wakati 2934 na 2863 cm-1 zinaunga mkono kunyoosha kwa C-H alifatiki. Bendi katika 1452, 1338, 1244, 1158, 936, 851 cm-1 zinaendana na njia za mifupa ya eneo la alama za vidole na mgeuko wa C-H, lakini hazimtambui kipekee Cycloheptanone.
Hatua zinazofuata zilizopendekezwa: Recollect the FTIR spectrum at higher signal quality and confirm the carbonyl band shape and exact position near 1700 cm-1. Check specifically for any weak O-H or N-H stretching bands above 3000 cm-1 to rule in or out alcohol- or amide/imide-containing alternatives suggested by some library candidates. Compare the sample against an authentic Cycloheptanone reference spectrum, focusing on the full fingerprint region rather than the carbonyl band alone. If confirmation is needed, use GC-MS or LC-MS to test whether the sample is a low-molecular-weight ketone such as Cycloheptanone versus another aliphatic carbonyl compound.
