Dipole moment of Rydberg states

Click For Summary
SUMMARY

The discussion centers on the electric dipole moment of Rydberg states for calcium fluoride (CaF) and barium fluoride (BaF). Participants reference K. P. Huber and G. Herzberg's "Constants of Diatomic Molecules" and the NIST Diatomic Spectral Database as key resources, although the latter may not include Rydberg states. The dipole moment is directly related to the slope of Stark shift splittings versus applied electric field, a concept that requires understanding of angular quantum numbers for deeper insights.

PREREQUISITES
  • Understanding of Rydberg states in diatomic molecules
  • Familiarity with electric dipole moments
  • Knowledge of Stark effect and its implications
  • Ability to interpret spectral data from databases
NEXT STEPS
  • Research the Stark effect in Rydberg atoms
  • Explore the NIST Diatomic Spectral Database for related data
  • Study the paper from Bob Field's group on dipole moments
  • Learn about angular quantum numbers and their role in dipole moments
USEFUL FOR

Researchers in molecular physics, experimental physicists studying diatomic molecules, and anyone interested in the properties of Rydberg states and their electric dipole moments.

Hello! Are there any experimental measurements or theoretical calculations of the electric dipole moment of any Rydberg state for CaF or BaF? Thank you!

Greetings,

The two most comprehensive compilations of physical constants of the electronic states of diatomic molecules of which I am aware are:

K. P. Huber and G. Herzberg, "Constants of Diatomic Molecules" Van Nostrand Reinhold, New York, 1979.

NIST Diatomic Spectral DatabaseES
 
I don't think the NIST database will have Rydberg states. It's a bit exotic.

I am confident that the information you want can be gleaned from this paper out of Bob Field's group. However, this stuff makes my head hurt. All I know is that the dipole moment is proportional to the slope of a plot of Stark shift splittings vs applied electric field. How that depends on the angular quantum numbers is where I get lost. @EigenState137 @amoforum @DrDu @BillKet are all people who are more comfortable than I am with this stuff.
