WebApr 23, 2016 · If intermolecular interaction (lattice energy etc.) can be neglected it reflects differences in the internal energy of the molecules. In your first example C has the smallest heat of combustion since it has the lowest internal Van der Waals strain. WebThe nuclear isomeric transition in thorium-229 appears to offer a solution to this problem. Because interactions in the nucleus occur at the MeV energy scale, as opposed to the eV scale in atomic measurements, a nuclear energy level is roughly times more sensitive to any variation in the fundamental constants.
