🔬 Molecular Vibrational Spectrum Simulator (2D)

2D Canvas2D simulation of a diatomic-like vibrational oscillator: tune the bond force constant and reduced mass, switch between the harmonic and Morse potential, and watch the real vibrational energy levels and resulting IR absorption spectrum update live.

⚙ Under the hood

Tune a diatomic bond's force constant and reduced mass, or pick a real molecule preset (H2O, CO2, CH4, HCl, NH3), and switch between the harmonic and Morse potential to watch the true vibrational energy levels and the resulting IR absorption line spectrum change live.
