Exactly Fran,
Once they start playing with variations on a theme (different harmonics/subharmonics), I think it will reveal subtleties which QM could only guess at (thus the probabilistic nature of QM). I hope they report other transition frequencies soon! 2,466,061,413,187,018 hertz 2.466061413187018 * 10^15 hertz 2.47 PetaHertz 3 PetaHz = Near UV, wavelength 100nm, just above the visible spectrum. Does the technology exist to control the frequency of a NUV laser to within a few Hz!!

It should reveal sub harmonics for manipulating h but regarding f/h it brings up an interesting question, does the spectrum broadening mean the fractional orbits are at different frequencies, and if so are they nice orbital steps ½ to 137? Or is the shift linear?

But theorists have yet to fully reconcile those laws with relativity, the other major foundation of modern physics. In Physical Review Letters, a multilaboratory collaboration reports improved hydrogen measurements that place limits on how big one possible correction to relativity could be. Researchers at the Max Planck Institute for Quantum Optics in Garching, Germany, have pioneered methods that connect optical emission frequencies to the much lower radio frequencies of atomic clocks. But the best atomic clocks, based on a fountain of cesium atoms, are in distant labs such as the Federal Physical-Technical Institute (PTB) in Braunschweig, and cant be easily moved. So the two labs synchronized their setups by sending light signals back and forth over a 920-km-long optical fiber. The connection allowed them to express the 1S-2S transition frequency in terms of the international standard definition of the second as 2,466,061,413,187,018 hertz, with an uncertainty of just 11 hertz. The researchers exploited the unprecedented precision to look for variations of the frequency over a year. Such variations would show that the frequency depends on the motion of the Earth around the Sun, which is forbidden by relativity. But the team estimates that parameters that quantify that dependence can be no larger than a few parts in 10^11. One of the parameters is slightly different from zero, but even more precise measurements will be needed to determine if this difference is truly significant.

Now you have an exact frequency with which to manipulate the H atom -Mark Iverson
