<Inga Fischer-Hjalmars> developed theoretical approaches to chemical bonding, including work with <Charles Alfred Coulson> on bond dissociation. Stretching a bond tests whether an approximate electronic description can represent the separated fragments correctly.
This links a calculation near equilibrium with its behaviour far from equilibrium. A model that works well near a minimum can fail when a bond breaks and several electronic configurations become important.https://www.iaqms.org/obituary/IngaFish-Hjalmar.pdf[IAQMS obituary by Björn Roos, 1947 dissociation collaboration]{ref}
