Undergrad Dipole moment of Rydberg states

Click For Summary
Experimental measurements or theoretical calculations of the electric dipole moment for Rydberg states in CaF or BaF are not widely documented. The NIST Diatomic Spectral Database is unlikely to contain information on these exotic states. A relevant paper from Bob Field's group may provide insights, particularly regarding the relationship between dipole moments and Stark shift splittings. Understanding how these dipole moments depend on angular quantum numbers can be complex. Further expertise from community members like @EigenState137, @amoforum, @DrDu, and @BillKet may be beneficial for deeper insights.

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.

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.

Thread 'Unexpected irregular reflection signal from a high-finesse cavity'

I am observing an irregular, aperiodic noise pattern in the reflection signal of a high-finesse optical cavity (finesse ≈ 20,000). The cavity is normally operated using a standard Pound–Drever–Hall (PDH) locking configuration, where an EOM provides phase modulation. The signals shown in the attached figures were recorded with the modulation turned off. Under these conditions, when scanning the laser frequency across a cavity resonance, I expected to observe a simple reflection dip. Instead...
