A teaching tape for LQ-07, Fluorescence Energy Budget and Stokes's Rule
Stokes's Rule as an Energy Budget
Walkthrough of Einstein's 1905 §7 energy accounting for fluorescence emission and its deviation cases.
Open LQ-07 with these settings
Where it starts
| Setting | Value |
|---|---|
| Exciting Frequency ν₁ (nu1) | 850 |
| Emitted Frequency ν₂ (nu2) | 850 |
| Absorbed Quanta k (multiQuantumK) | 1 |
| Absorbed Optical Power (absorbedPowerMicrowatts) | 1 |
| Quantum Yield Y (quantumYield) | 0.5 |
What it changes, and what to expect
Set Emitted Frequency ν₂ (nu2) to 900 changes what the run starts from
Anti-Stokes Disallowance
Emitting at nu2 = 900 THz requires 3.722 eV, exceeding the absorbed quantum.
Set Absorbed Quanta k (multiQuantumK) to 2 changes what the run starts from
Multi-Quantum Absorption
If k = 2 quanta are absorbed per process, 7.031 eV is available.
These are the values the tape's author recorded, not a result this page computed. Nothing here runs the instrument. Open LQ-07 with these settings: the link opens it with them already in place. Compare what it gives you with what is recorded here. The settings travel in the link and the laboratory reads them as it loads, so without JavaScript it opens at its worked example instead.
