We are told to assume only one vibrational mode. I was wrong before. Since we assume one vibration mode we can approximate the energy level spacing as a particle in a box. The length of the box is 5micrometeres, as that is the length of the particle. I still don't know how to relate the...

Spacing Between energy levels. In a QM vibration model the spacing between levels is 2B. So if we know the wavelength a transition corresponds to we can find the spacing between the levels. There are two problems, I don't know this relation and I don't know how to calculate B for anthracene.

Homework Statement The fluorescence spectrum of anthracene vapor in the figure shows peaks with maxima at 440 nm, 410 nm, 390 nm, and 370 nm, whereas the absorption spectrum has peaks at 360 nm, 345 nm, 330 nm, and 305 nm. Assuming that only one vibrational mode contributes to these...
