Infrared spectrum comparison chart. Analysis result: Propylcyclohexane.

The sample is identified as propylcyclohexane, a saturated cyclic hydrocarbon, based on a high-confidence library match (Propylcyclohexane, similarity 0.996) and the presence of characteristic aliphatic C-H stretching and bending bands. The spectrum lacks evidence for aromatic, oxygen-containing, or nitrogen-containing functional groups, confirming a pure hydrocarbon composition. The dominant bands arise from long methylene chains, consistent with a cycloalkane or linear alkane

Conclusion

Literature sources consistently assign the 2926, 2858, and 1376 cm⁻¹ bands to aliphatic hydrocarbon moieties [1][2][4].
The strong bands at 2926 and 2858 cm⁻¹ arise from asymmetric and symmetric C–H stretching of methylene (CH₂) groups, respectively [4][2].
The absorption at 1460 cm⁻¹ corresponds to CH₂ scissoring, and the band at 1376 cm⁻¹ is assigned to symmetric CH₃ bending, both consistent with a saturated alkane backbone [1].

Limitations

Evidence that limits the conclusion

One literature source attributes the 1460 cm⁻¹ band to an aromatic group [3]; however, this conflicts with the absence of other aromatic features and the overall aliphatic character of the spectrum.
The presence of minor branching or trace unsaturation cannot be ruled out solely from the four observed bands.
The exact chain length and cyclic versus linear structure remain partially ambiguous, as the spectral signature is similar for long-chain alkanes and cycloalkanes.

Recommendation

Suggested next verification

Verify the identity and purity using gas chromatography–mass spectrometry (GC–MS) or nuclear magnetic resonance (NMR) spectroscopy to confirm the cyclic alkane structure and assess chain length.
If the sample is a mixture, additional purification steps may be needed to isolate the major component for definitive characterization.
