How it works

Each bond is a spring between two atomic masses; its natural vibration wavenumber is set by the bond's stiffness (force constant k) and the reduced mass μ of the two atoms it joins:

ṽ = 1/(2πc) · √(k/μ)

Stiffer bonds and lighter atoms vibrate faster (higher ṽ). Here every ball-and-stick bond oscillates along its own axis at a speed scaled from its real wavenumber, so O–H (≈3400 cm⁻¹) visibly flickers fastest, C–H (≈2950) close behind, then C=O, aromatic C=C, N=O, and S=O (≈1150) slowest — the same ordering a real spectrometer would report as peak position.

Bond-mix sliders — the same fingerprint controls as the sample spectrum; they drive which library molecule is judged the best match and which of its bonds glow brightest (weighted by how much that channel contributes).
Vibration amplitude — a visual-only exaggeration control; real bond stretches are picometres, far too small to see, so amplitude is scaled up for clarity while relative frequencies stay physically ordered.
Model geometry — a simplified ball-and-stick structure of the matched reference compound (methane, ethanol, formaldehyde, acetic acid, benzene, NO₂ or SO₂), colour-coded by element.

Real-world relevance: pairing a matched IR/Raman fingerprint with the actual 3D geometry it came from is exactly how a spectroscopist confirms a candidate identification isn't just a coincidental peak overlap — the vibrating bonds must belong to a structurally sensible molecule.
