Enhanced sensitivity to variations of fundamental constants in highly charged molecules from analytic perturbation theory
Carsten Zülch, Konstantin Gaul, Robert Berger
Quasi-forbidden electronic transitions in atoms and vibronic transitions between quasi-degenerate states in molecules serve as powerful probes of hypothetical temporal variations o…

Pinning down electron correlations in RaF via spectroscopy of excited states and high-accuracy relativistic quantum chemistry
M. Athanasakis-Kaklamanakis, S. G. Wilkins, L. V. Skripnikov +53
We report the spectroscopy of the 14 lowest excited electronic states in the radioactive molecule radium monofluoride (RaF). The observed excitation energies are compared with full…
