This dataset is a spectroscopic library structured as a document database. It contains Raman and ATR-FTIR spectra of weathered and biofouled polymers.

The deposit here includes only the chemical raw data (spectra.zip) and the related metadata (metadata.json). Readers are recommended to visit the source repository of the project (https://github.com/robna/MPX_specDB), which includes also an interactive app that can be used to view or selectively download the data. It also provides more in depth explanations on methodology and extensive metadata descriptors.

Vibrational spectroscopic measurements of polymers weathered and biofouled in the marine environment.

Raw spectroscopic data have been converted from various proprietary instrument formats into a standardised CSV format. The accompanying metadata provides information on the post-processing steps applied to each spectrum.
