Spectroscopy Simulator – IR, NMR & UV-Vis Online Lab

Spectroscopy provides the primary experimental evidence for molecular structure, with each technique probing a different aspect of a molecule's interaction with electromagnetic radiation. This simulation covers IR spectroscopy for functional group identification, ¹H NMR for connectivity, and UV-Vis for electronic transitions — the three-technique toolkit of modern structure elucidation.

What you can do in this simulation

• Load an organic molecule and generate its simulated IR spectrum with key absorption assignments
• Identify characteristic IR absorptions: O-H stretch ~3300 cm⁻¹, C=O ~1715 cm⁻¹, N-H bends
• Analyze a simulated ¹H NMR spectrum: chemical shifts, splitting patterns, and integration ratios
• Explore UV-Vis absorption of conjugated systems and apply Beer-Lambert law to find concentration
• Solve structure determination problems by combining IR, NMR, and UV-Vis data
