Data Sources

• PubChem (NIH/NLM) — molecular structures, IUPAC names, and 3D coordinates used across stereochemistry, nomenclature, and other modules.
• Hans Reich Collection (© ACS Division of Organic Chemistry) — A-value reference data for chair conformation energy problems.
• Daniel Lowe USPTO Dataset — reaction data used in literature reaction examples.
• nmrshiftdb2 (CC BY-SA 4.0) — published experimental chemical-shift assignments from which the spectra in the NMR assignment, integration, and DEPT modules are reconstructed.
• Beilstein Journal of Organic Chemistry (CC BY 4.0) — published HRMS measurements underlying the exact-mass and adduct-identification modules; each problem cites its source article after you answer.
• Chemotion / RADAR4Chem IR collection (CC BY-SA 4.0) — measured ATR-FTIR spectra underlying the IR module's curve-based problems. Spectrum-derived data shown on those problems is likewise available under CC BY-SA 4.0, distinct from the site's CC BY-NC content license.

Open-Source Tools

• RDKit — cheminformatics toolkit used for 2D structure rendering and molecular computations.
• 3Dmol.js — interactive 3D molecular viewer used in stereochemistry modules.

AI Tools

• Google Gemini — powers Socratic hint generation for IUPAC nomenclature problems.
• Claude (Anthropic) — assisted with site development.
