Resumen:
In this talk, I will introduce the most precise theoretical formalism for describing molecular properties, especially crucial for the study of atomic and molecular systems containing heavy elements. This framework, that of relativistic quantum mechanics, generalized by quantum electrodynamics, allows spectroscopic parameters to be predicted with very high precision. In particular, I will show how the nonrelativistic formulations are weakened in heavy systems and how it is possible to generalize well-known relationships between properties in the relativistic context.
