• Mechi bora ya maktaba: Mafuta ya Sassafras #151435

• Bendi dhaifu katika 2071 cm⁻¹ haina maelezo wazi katika muktadha wa mchanganyiko wa kikaboni wenye oksijeni na inaweza kutokana na uchafu mdogo, C-O iliyonyonywa, au kikundi cha kazi kisicho cha kawaida.
• Usaidizi wa moja kwa moja wa fasihi kwa vikundi vya N–H (3420 cm⁻¹, [2]) hautarajiwi kwa mafuta ya kawaida ya sassafras (hasa C, H, O) na unapendekeza uwezekano wa uchafu wa amini/amide au maelezo mabaya.
• Kilele katika 1646 cm⁻¹ kinaweza pia kufasiriwa kama kupinda kwa O–H kwa maji, na bendi pana ya 3420 cm⁻¹ inaweza kutawaliwa na unyevu, ikificha habari maalum za muundo.
• Hakuna bendi za alama zisizo na shaka (k.m., C–Cl, C≡N, mchoro thabiti wa karbonili) zilizoweza kuthibitishwa na ushahidi uliopo, na kuacha asili kamili ya kemikali bila kutatuliwa.

Hatua zinazofuata zilizopendekezwa: Perform gas chromatography–mass spectrometry (GC‑MS) to identify volatile organic constituents and confirm or refute the presence of sassafras oil components such as safrole. Obtain a reference FTIR spectrum of authentic Sassafras oil for direct comparison under identical measurement conditions. Use complementary techniques such as Raman spectroscopy or NMR to resolve the ambiguity between alkene unsaturation, carbonyl groups, and moisture contributions.
