I want to see if there is any patterns in the frequencies. Maybe you could predict the frequency of an isotope or maybe other information. I know other people must of looked at this but I am still curious. How can I find this paper? Thanks.
If caesium 133 frequency for its hyperfine structure is 9 192 631 770, and hydrogen is 1 420 405 751.7667 what are the frequencies for the other elements and their isotopes? Is there a list on line some were because this would be a long list. Any help on where to look on line would be...
