- **Peak at 1012 cm⁻¹ (strong, sharp):** This strong, sharp absorption in the 1000–1100 cm⁻¹ range is characteristic of a **C–O stretch**, most likely from an **alcohol, ether, or ester**. Its strength and sharpness suggest it is a primary vibrational mode of the molecule, possibly from a **primary or secondary alcohol** or an aliphatic ether.
- **Peak at 1373 cm⁻¹ (weak, sharp):** This weak, sharp peak is typical of a **symmetrical methyl bending vibration (δ CH₃)**. Its weakness indicates methyl groups are not the dominant feature but are present, often seen near 1375 cm⁻¹ in many organic compounds like alkanes or methyl-substituted molecules.
- **Peak at 3284 cm⁻¹ (weak, broad):** A broad absorption in the 3200–3600 cm⁻¹ region is a classic signature of an **O–H stretch**, specifically from a **hydrogen-bonded alcohol or phenol**. The breadth is due to hydrogen bonding, and its relative weakness here may indicate dilution or a less concentrated O–H environment.
**Potential Structure Conclusion:** The spectrum is consistent with an **alcohol-containing compound**, likely a **primary or secondary aliphatic alcohol**. The strong C–O stretch at 1012 cm⁻¹ and the broad O–H stretch at 3284 cm⁻¹ together strongly indicate an alcohol functional group. The weak methyl bend at 1373 cm⁻¹ suggests the presence of methyl groups, possibly in an alkyl chain (e.g., ethanol, propanol, or similar). The absence of strong carbonyl (C=O, ~1700 cm⁻¹) or other prominent peaks narrows the likely identity to a simple alcohol without additional major functional groups.
