Infrared spectrum comparison chart. Analysis result: inorganic carbonate-containing material.

The current FTIR evidence does not support a firm identification of the sample as the top library hit. The observed bands at about 709, 870, and 1396 cm-1 are more consistent with a carbonate-containing inorganic material than with the specific retrieved compound barium(+2) cation; trifluoromethanesulfonate. The library result is low-confidence and internally inconsistent across the top candidates, so the safest conclusion is a broad carbonate-containing inorganic direction rather than a specific entity assignment

Conclusion

inorganic carbonate-containing material

General assessment

#47816 Initial rank 1 Current rank 1 Library lead match 0.0%

Conclusion

The observed 1396 cm-1 band supports a strong carbonate stretching vibration.
The accompanying bands near 870 and 709 cm-1 support the same carbonate-containing interpretation.
The peak set is more consistent with an inorganic salt-like material than with an organic compound requiring multiple distinct C-H, C-F, or aromatic features.

Main limitation

The top library identification as barium(+2) cation; trifluoromethanesulfonate is not directly supported by characteristic evidence for trifluoromethanesulfonate, such as a richer sulfur-oxygen and carbon-fluorine band pattern.

The accompanying bands near 870 and 709 cm-1 support the same carbonate-containing interpretation.
The peak set is more consistent with an inorganic salt-like material than with an organic compound requiring multiple distinct C-H, C-F, or aromatic features.
The sample shows three prominent absorptions near 709, 870, and 1396 cm-1.
This band pattern is characteristic of carbonate vibrations, especially the strong band near 1396 cm-1 with accompanying lower-wavenumber bands near 870 and 709 cm-1.
The leading library candidate is barium(+2) cation; trifluoromethanesulfonate, but the match confidence is 0 and the Top-15 list contains chemically unrelated materials, indicating a weak retrieval basis.
The Top-15 pattern includes fluorinated polymers, chlorinated aromatics, sulfur-oxygen compounds, and phosphates, which does not provide a coherent narrow material assignment for this sample.

Limitations

Evidence that limits the conclusion

The top library identification as barium(+2) cation; trifluoromethanesulfonate is not directly supported by characteristic evidence for trifluoromethanesulfonate, such as a richer sulfur-oxygen and carbon-fluorine band pattern.
The sample peak list does not show reported support for features expected for chlorinated polyphenyls or poly(vinylidene fluoride), despite those also appearing among the leading library candidates.
Because the top candidates are chemically diverse and all have zero similarity, the library search does not provide a reliable narrow identification.
FTIR alone, from the limited reported peaks, cannot determine which carbonate-containing inorganic material is present.
The present evidence does not distinguish confidently among possible carbonate salts or mixtures.
No direct literature match or reference spectrum confirmation is available for the current sample.

Recommendation

Suggested next verification

Compare the full spectrum against reference spectra for common inorganic carbonates, especially barium carbonate and calcium carbonate, because the observed band positions are compatible with carbonate salts.
Check the sample by Raman spectroscopy or X-ray diffraction to distinguish specific crystalline carbonate phases.
If elemental analysis is available, verify whether barium, calcium, magnesium, or sodium is present to narrow the carbonate assignment.
Re-examine the full FTIR spectrum for additional bands outside the reported peak list, particularly any sulfur-oxygen or carbon-fluorine absorptions that would be required to support trifluoromethanesulfonate.
