• Mechi bora ya maktaba: 2-methylpropanoyl 2-methylpropanoate #29632 | match 0.0%

1. Bendi za 992 na 1021 cm-1 zinaendana na utendaji wa kikaboni wenye C-O.
2. Maktaba Top-15 ina wagombea wengi wenye oksijeni, ambayo inaambatana na mwelekeo wa nyenzo ya kikaboni yenye oksijeni.
3. Jina la maktaba Top-1, 2-methylpropanoyl 2-methylpropanoate, lenyewe ni kiwanja chenye oksijeni, kwa hivyo mwelekeo mpana wa oksijeni unalingana na urejeshaji.
4. Bendi mbili tu za sampuli zinapatikana, kwa 992 na 1021 cm-1, ambazo ni chache sana kwa mgawo salama wa molekuli.
5. Utafutaji wa maktaba ulirudisha 2-methylpropanoyl 2-methylpropanoate kama Top-1, lakini kufanana kote iliyoripotiwa ni 0.000, kwa hivyo mechi haitofautishi kwa kiasi.
6. Mchoro mpana wa maktaba Top-15 unajumuisha wagombea kadhaa wenye oksijeni na maelewano ya maktaba yanataja oksijeni heterosikli / pete 6m, lakini mchoro huu hauna nguvu ya kutosha kuhitaji mgawo wa pete kwa sampuli ya sasa.
7. Bendi zilizozingatiwa zinaanguka katika eneo linalohusishwa kwa kawaida na kunyoosha kwa C-O au mitetemo ya mifupa ya eneo la alama za vidole katika misombo ya kikaboni yenye oksijeni.
8. Hakuna taarifa ya kumbukumbu ya moja kwa moja au ushahidi wa fasihi unaohusiana unaounga mkono kiwanja maalum cha Top-1.

• Ujasiri wa maktaba ni mdogo, na thamani za kufanana zilizoripotiwa sifuri kwenye hiti zinazoongoza.
• Sampuli haionyeshi bendi za kutosha zilizoripotiwa kuunga mkono mgawo maalum wa Top-1 wenye kabonili.
• Maelewano ya maktaba yanayopendekeza heterosikli ya oksijeni au pete yenye wanachama sita hayaungwi mkono moja kwa moja na vilele viwili vilivyoripotiwa pekee.
• Mgawo wa esta yenye kabonili bado haujathibitishwa kwa sababu hakuna bendi ya tabia ya kabonili iliyoripotiwa.
• Heterosikli ya oksijeni yenye pete haiwezi kuthibitishwa kutoka kwa orodha ya sasa ya vilele.
• Kwa bendi mbili tu za eneo la alama za vidole, nyenzo kadhaa tofauti za kikaboni zenye oksijeni bado zinawezekana.

Hatua zinazofuata zilizopendekezwa: Recollect the full FTIR spectrum over the standard mid-IR range and verify whether a strong carbonyl band near about 1735-1810 cm-1 is present; this is critical for testing the Top-1 ester-like candidate. Check for broader C-H stretching and fingerprint features to distinguish a simple oxygenated aliphatic compound from a cyclic ether or other oxygen-containing material. If the sample amount permits, confirm composition with GC-MS or LC-MS to determine whether a discrete low-molecular-weight oxygenated compound such as 2-methylpropanoyl 2-methylpropanoate is actually present. If a ring-containing oxygenated material is suspected, compare against a reference spectrum with full-band matching rather than relying on the two currently listed peaks.
