Polarization Effects and Ionic Bonding in a Polar Diatomic: the CaF^+ x {}^ 1 Sigma^+ State Conference Paper uri icon

abstract

  • Abstract Core multipoles and polarization effects affect the term values and spectroscopy of Rydberg states, and, conversely, Rydberg state spectroscopy provides a window into the nature of ground electronic state charge distributions, and into polarization due to configuration interaction. As experimental resolution continues to increase through the introduction of techniques like chirped mm-wave techniques for Rydberg systems, more details about the core electronic structure as a function of Rydberg state quantum numbers (n, l) and internuclear separation, R, will become available. Existing modeling of the CaF Rydberg spectrum, although extensive, is not ready for the challenge of higher resolution measurements. Even for the existing data, MQDT calculations (based on a two center effective potential with limited atomic polarization) show reasonable agreement at …
