... prefers neighboring spins to be oppositely aligned. If we consider a triangular plaquette and anti-align two of the spins, then the third spin is frustrated in that whichever way it points, it is unable to simultaneously satisfy all of its interactions. In contrast, the same interaction on a square ...

Franck–Condon principle
The Franck–Condon principle is a rule in spectroscopy and quantum chemistry that explains the intensity of vibronic transitions. Vibronic transitions are the simultaneous changes in electronic and vibrational energy levels of a molecule due to the absorption or emission of a photon of the appropriate energy. The principle states that during an electronic transition, a change from one vibrational energy level to another will be more likely to happen if the two vibrational wave functions overlap more significantly.
