Yes — batch 48 (LBN 48 / Sample P 76 B.NO 48) has NMR. The record links two NMR spectral plots run in CDCl3, dated 25 December 2025:

• 1H FS (full spectrum) plot
• 13C zoom2 plot

Both sit under the "Analytical Report / NMR / #48" folder. The record's date and scientist fields are sourced from the 1H plot, and samples[2] references the 13C plot. These are the spectral images themselves; the record doesn't extract individual peak assignments, integrals, or a written NMR report — just the plot PDFs and their metadata.
