Conclusion

aromatic / amide

Library direction
مجموعی اعتماد
#16203 Initial rank 1 Current rank 1 Library lead match 74.7%
Conclusion
  1. Direct literature evidence assigns the 1416 cm⁻¹ band to aromatic C–C stretching [7] and the 1290 cm⁻¹ band to C–O stretching [2], reinforcing the proposed ester/ether framework.
  2. The cited report assigns the 1096 cm⁻¹ region to ν(COC) vibrations, consistent with ether functionalities [40].
  3. The strong band at 1734 cm⁻¹ corresponds to carbonyl (C=O) stretching, typical of carboxylic acid esters or acids [1].
Main limitation

A band at 956 cm⁻¹ is literature-attributed to metal‑oxo vibrations [6], and a signal at 1180 cm⁻¹ is assigned to fluorine-containing moieties [4]; these features are not expected in a maleic acid copolymer and may indicate inorganic contamination or sample heterogeneity.

Evidence supporting the conclusion

Only sample-relevant statements that support the present conclusion are shown here.

  1. The FTIR spectrum is most consistent with an oxygen-rich polymer material featuring carbonyl (ester/carboxylic acid), ether, aliphatic, and aromatic/amide moieties, best matches to Poly(methyl vinyl ether:maleic acid) in the library with moderate confidence.
  2. Direct literature evidence assigns the 1416 cm⁻¹ band to aromatic C–C stretching [7] and the 1290 cm⁻¹ band to C–O stretching [2], reinforcing the proposed ester/ether framework.
  3. The cited report assigns the 1096 cm⁻¹ region to ν(COC) vibrations, consistent with ether functionalities [40].
  4. The strong band at 1734 cm⁻¹ corresponds to carbonyl (C=O) stretching, typical of carboxylic acid esters or acids [1].
  5. The intense absorbance near 1096 cm⁻¹ is assigned to ν(COC) asymmetric/symmetric stretching in PEO-PVC electrolyte systems [40], indicative of ether linkages.
  6. Aliphatic C–H stretching bands at 2846, 2913, and 2944 cm⁻¹, together with deformation bands near 1367 cm⁻¹ [8] and 1416 cm⁻¹, confirm the presence of alkyl chains.
  7. Aromatic C–H stretching at 3031 cm⁻¹ and skeletal modes at 1557 and 1472 cm⁻¹ indicate aromatic ring contributions, while the 1637 cm⁻¹ band is consistent with amide I vibrations [2].
  8. Bands at 1257 and 1290 cm⁻¹ are attributable to C–O stretching vibrations, further supporting ester/ether structures [2].
  9. Major peak assignments include 1096: Related literature: ν(C-O-C) ether stretch | Direct reference: c o single bond; alkyl c h | Quality: The spectrum edges look truncated or baseline-shifted; 1180: Direct reference: c o single bond; alkyl c h | Quality: The spectrum edges look truncated or baseline-shifted; 1132: Direct reference: c o single bond; alkyl c h | Quality: The spectrum edges look truncated or baseline-shifted; 802: Related literature: Si-O-Si / siloxane potential | Direct reference: c o single bond; alkyl c h | Quality: The spectrum edges look truncated or baseline-shifted.
Limitations

Evidence that limits the conclusion

  • A band at 956 cm⁻¹ is literature-attributed to metal‑oxo vibrations [6], and a signal at 1180 cm⁻¹ is assigned to fluorine-containing moieties [4]; these features are not expected in a maleic acid copolymer and may indicate inorganic contamination or sample heterogeneity.
  • The broad N–H/O–H absorption envelope between 3000 and 3600 cm⁻¹ and the possible amide bands at 1637 and 1557 cm⁻¹ suggest the presence of nitrogen-containing functional groups, which are absent in the top library hit; the material may be a modified, contaminated, or more complex polymer system.
  • Library confidence is moderate (75%), and the direction label ‘aromatic / amide’ reflects the need for a broader classification given the mixed evidence.
Recommendation

Suggested next verification

  • Acquire complementary data (e.g., Raman spectroscopy, elemental analysis, or thermal analysis) to clarify the nature of the nitrogen-containing and inorganic components.
  • Perform a hydrolysis experiment to verify the presence of maleic acid units and assess the polymer backbone.
