Infrared spectrum comparison chart. Analysis result: oxygenated organic material with C–O bonding and multiple O–H/N–H-type bands.

The library’s nearest named match is Poly(vinyl formal), but the match quality is effectively non-discriminating and is not supported by direct reference or related-literature evidence. The sample instead supports only a broader oxygenated organic material direction. Bands near 1017, 1058, and 1105 cm⁻¹ are consistent with C–O stretching, while the cluster of high-wavenumber bands from 3283 to 3808 cm⁻¹ indicates substantial O–H and/or N–H-type absorption. Weak aliphatic C–H stretching is present near 2963 and 2999 cm⁻¹. This evidence is too nonspecific to justify a firm assignment to Poly(vinyl formal) or to the nitrogen-heterocycle pattern suggested by the noisy top-15 library spread

Conclusion

oxygenated organic material with C–O bonding and multiple O–H/N–H-type bands

General assessment

#7118 Initial rank 1 Current rank 1 Library lead match 0.0%

Conclusion

Top-ranked library hit is Poly(vinyl formal), so it remains the nearest named library candidate.
C–O stretching evidence is supported by the bands at 1017, 1058, and 1105 cm⁻¹.
The high-wavenumber band cluster supports the presence of hydroxyl and/or amine-type functionality.

Main limitation

All listed library candidates have 0.000 similarity, so the retrieval does not provide a reliable specific identification.

Top-ranked library hit is Poly(vinyl formal), so it remains the nearest named library candidate.
C–O stretching evidence is supported by the bands at 1017, 1058, and 1105 cm⁻¹.
The high-wavenumber band cluster supports the presence of hydroxyl and/or amine-type functionality.
Weak aliphatic C–H stretching near 2963 and 2999 cm⁻¹ supports an organic material rather than a purely inorganic phase.
The sample shows prominent fingerprint-region absorption at 1017, 1058, and 1105 cm⁻¹, which supports C–O single-bond functionality.
Multiple bands between 3283 and 3808 cm⁻¹ indicate hydroxyl-rich and/or amine-like stretching contributions, possibly including free and hydrogen-bonded forms.
Aliphatic C–H stretching is limited to bands near 2963 and 2999 cm⁻¹, supporting an organic matrix but not a specific polymer identity.
Bands at 1633, 1682, 1693, and 1706 cm⁻¹ suggest additional unsaturation, carbonyl-like absorption, adsorbed water contribution, or mixed components, but they do not uniquely identify the material.
The many narrow features in the 2171–2406 cm⁻¹ region are not a reliable basis for assigning a specific compound here and may reflect atmospheric or measurement-related contributions rather than sample-defining structure.

Limitations

Evidence that limits the conclusion

All listed library candidates have 0.000 similarity, so the retrieval does not provide a reliable specific identification.
Related-literature evidence is unavailable and does not narrow the assignment.
The top-15 library pattern is chemically inconsistent, mixing polymeric, chlorinated, phosphorus-sulfur, hydrocarbon, and silicate-like candidates, so its consensus is not trustworthy for a narrow conclusion.
The proposed nitrogen-heterocycle direction is not convincingly supported by the observed peak set.
It remains unclear whether the broad high-wavenumber absorption is dominated by O–H, N–H, water, or a mixture of these contributions.
The 1633–1706 cm⁻¹ region is not sufficiently resolved to determine whether a true carbonyl-containing component is present.
The current evidence cannot distinguish between an oxygenated polymer, resin, additive-containing organic film, or a mixed/contaminated sample.

Recommendation

Suggested next verification

Recollect the FTIR spectrum after improved background subtraction and atmospheric compensation, especially to reduce interference in the 2171–2406 cm⁻¹ region.
Inspect the 3200–3800 cm⁻¹ and 1600–1750 cm⁻¹ regions with higher signal-to-noise and full-spectrum review to separate hydroxyl, amine, water, and possible carbonyl contributions.
If this is a polymer or coating sample, compare against authenticated spectra of Poly(vinyl formal) and other oxygenated polymers using full-spectrum overlay rather than library rank alone.
Acquire complementary data such as Raman spectroscopy, DSC, or pyrolysis-GC/MS if a specific polymer or formulation identity is required.
