Dataset description

This repository contains the dataset associated with the paper “Tracking the chemical life histories of spruce resin-beeswax mixtures through degradation experiments using reflectance-mode FTIR”. It includes FTIR spectra from Experiment 49 processed with Kramers-Kronig transformation (KKT), auto-baseline correction (function fit method, quadratic correction order, data normalized to a zero baseline minimum), CO₂ band removal, and smoothing with a 17-point Savitzky-Golay (SG) filter (quadratic/cubic algorithm). Averaged spectra for each sample as described in the manuscript are also included. Spectra for an unaltered, pristine spruce resin-beeswax on flint control sample are provided as well. All FTIR spectra are provided in CSV format.

Questions before production use

Practical answers on evaluation, licensing, freshness, versioning and support.

Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.

Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.

Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.

Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
