Max Born - 2024 ACF Winter

Question

This scientist and Huang Kun name an approximation that improves on an earlier result by better accounting for diagonal nonadiabatic effects. For 10 points each:

[10m] Probability density is proportional to the wavefunction-squared by what scientist’s namesake rule? An approximation that separates the wavefunctions of nuclei and electrons is named for this scientist and Oppenheimer.

ANSWER: Max Born [accept Born–Huang approximation or Born–Oppenheimer approximation or Born rule]

[10e] The Born–Oppenheimer approximation is based on the fact that this quantity for the nucleus is much larger than that of the electron. For an atomic nucleus, this quantity can be measured in daltons or amu.

ANSWER: atomic mass [or molecular mass; prompt on weight]

[10h] The Born–Oppenheimer approximation can be extended to derive this other doubly-eponymous principle, which says that electronic transitions occur without significant changes in the molecule’s nuclear configuration.

ANSWER: Franck–Condon principle
