I have enough to answer. Batch 25 II matched "IR" only as a substring (not an IR spectrum) — no IR document links to it. Only two IR spectra documents exist.

Answer

Two samples have IR spectra on file in this data drop:

1. BYK 9076 STD — record exp-9076-000BYK9076STD (the vendor standard run), linked to the analytical document IR BYK 9076 STD.pdf (role: analytical, alias match "BYK 9076 STD").
2. SAW #19 976030726B — record exp-9076-000SAW199760307, linked to the analytical document IR SAW #19 976030726B.pdf (role: analytical, alias match "SAW #19 976030726B").

Both IR documents sit under pdf/9076 Data for Raven POC project/Analytical Report/IR/ and are the only two IR files in the corpus (a copy tree holds duplicates of the same two).

GAP / note: A third record, exp-9076-025II (alias "25-II"), surfaced in a text search for "IR", but that is a false match — the substring "IR" occurs inside the record's text; its only backing document is the summary table 28112025 9076 Expt Table 2025.xls, and the record carries no IR/FTIR characterization and no linked IR document. So Batch 25 II has no IR spectrum on file. No other sample in the record set references an IR or FTIR spectrum.
