reported peaks (cm⁻¹): 183, 222, 354, 612, 870
Visual inspection inconclusive. Composition cannot be assigned within current reference frameworks. The Raman peak at 612 cm⁻¹ matches the unattributed feature reported in AM-2019-04471-A and AM-2016-00744-A; no structural model has been proposed for the joint occurrence across three specimens of dissimilar provenance. The peak at 870 cm⁻¹ has not been observed elsewhere in the registry. Non-destructive analysis ongoing. Record kept under active observation pending re-submission of supporting documentation.
Events recorded against this accession in the registry's printed custody book. Operator initials are anonymous. Storage codes follow the convention vault-shelf-drawer.
