RamanBiolib: Open Raman spectral library for biomolecule identification

This library contains Raman spectra and peak-position lists for 140 biological components (lipids, proteins, carbohydrates, amino acids, metabolites, nucleic acids, pigments). Spectra are smoothed, baseline-corrected, interpolated to 450–1800 cm⁻¹ at 1 cm⁻¹ steps, and min–max normalized, with accompanying measurement metadata. It is designed for biomolecule identification through spectral-similarity or peak-matching searches.
