Top15

Similarity-ranked Top-15 library comparison

Library spectrum will appear here.

Infrared spectrum comparison chart. Analysis result: Organic material with aromatic and alkene unsaturation, likely containing C–O single bond functionality; the presence of carbohydrate or silicate components cannot be excluded.

reference library comparison points to an aromatic/alkene character enriched in oxygenated groups, but only a single band at 1016 cm⁻¹ is available, preventing a more specific identification. This band is consistent with C–O stretching, while direct evidence raises possibilities of carbohydrate and silicate contributions

Conclusion

Organic material with aromatic and alkene unsaturation, likely containing C–O single bond functionality; the presence of carbohydrate or silicate components cannot be excluded

General assessment

समग्र आत्मविश्वास

#15455 Initial rank 1 Current rank 1 Library lead match 71.7%

Conclusion

Direct literature explicitly assigns the 1016 cm⁻¹ band to C–O and C–O–C stretching vibrations [1], and the same source reports groups including carbohydrate, methyl, and siloxane in a starch‑derived system.
The only sample peak at 1016 cm⁻¹ is consistent with C–O single bond stretching, a vibration common to esters, ethers, and carbohydrates [1].
The library top‑15 consensus suggests supporting groups such as methacrylate, acetate, and aromatic features, aligning with an oxygenated organic material having alkene/aromatic character.

Main limitation

The library top‑15 includes silicates and phosphoranes, indicating potential inorganic contributions that extend beyond a strictly organic aromatic/alkene material.

Direct evidence also lists methyl, aromatic, silicon–oxygen, siloxane, and carbohydrate among the groupings supported in the literature, broadening the plausible composition.
Major peak assignments include 1016: Related literature: aromatic ring deformation (polyaniline B ring) | Direct reference: c o single bond; alkyl c h.

Limitations

Evidence that limits the conclusion

The library top‑15 includes silicates and phosphoranes, indicating potential inorganic contributions that extend beyond a strictly organic aromatic/alkene material.
A related literature report attributes 1016 cm⁻¹ to ring deformation of the B ring in polyaniline (aromatic amine), a chemically different system, but this single‑source assignment does not align with the broader library consensus or the direct C–O evidence.
Only one spectral feature is available; bands characteristic of carbonyl (C=O) near 1700 cm⁻¹ and aromatic/alkene C–H stretching above 3000 cm⁻¹, which would be required to confirm an ester‑type structure, are absent from the present data.
The library lead gap is narrow (0.013), and the top‑15 candidates span organic esters, silicates, and phosphoranes, indicating that the retrieved library neighbours do not unify on a single narrow material class.

Recommendation

Suggested next verification

Acquire a full mid‑IR spectrum covering the 4000–400 cm⁻¹ region to observe the carbonyl, aromatic C–H, and Si–O stretching regions, which would differentiate organic ester/anhydride from silicate or carbohydrate materials.
Perform complementary analysis (e.g., GC‑MS, NMR, or X‑ray fluorescence) to resolve the exact molecular identity and any inorganic content.
