The phrase "atomic frequencies" is correct and usable in written English.
It can be used in scientific contexts, particularly in physics or chemistry, to refer to the specific frequencies associated with atomic transitions or emissions.
Example: "The study focused on the atomic frequencies emitted by the hydrogen atom when it transitions between energy levels."
Alternatives: "atomic resonance frequencies" or "atomic emission frequencies".
Dehmelt and his colleagues went on to develop methods for measuring atomic frequencies and individual quantum jumps (the transitions between atomic energy levels) with unprecedented precision.
Furthermore, when combined with previous measurements, we find no time variations of these atomic frequencies within the uncertainties of the absolute value of( partial differential f(Ca)/ partial differential t)/f(Ca) < or =8 x 10 -14 10 -14) and the absolute value of(partial differential f(Hg)/ partial differential t)/f(Hg) < or =30 x 10(-14) yr -1).
The extremely accurate value obtained by Essen and Parry for the frequency of the cesium atom in 1958 provided a new standard for measuring time, called atomic time, and was eventually (1967) used to redefine the standard SI unit of time, the second, in terms of atomic frequencies.
Although the INDO calculation is known not to yield accurate values for the vibrational force constants, we find nevertheless that a comparison of calculations for the cation and atom suggest that the solvated atomic frequency ought to lie only slightly below that of the solvated cation.
We present a compact atomic frequency standard based on the interrogation of magnetically trapped 87Rb atoms.

The Symposium highlights manufacturing methods and technologies that realize emerging products in MEMS resonator-based devices, quartz micro-clocks, and advanced atomic frequency standards.
We are developing laser frequency measurement technologies that should allow us to construct an optical frequency synthesis system capable of measuring optical frequencies with a precision limited by the atomic frequency standards.
For a neutral (40 Ca-based optical frequency standard we report a fractional frequency instability of 40 Ca-based in 1 s, which represents a fivefopticalrovement over existing atomic frequency standards.
