The nonresonant (NR) corrections are estimated for the most accurately measured two-photon transition 1s-2s in the hydrogen atom. These corrections depend on the measurement process and set a limit for the accuracy of atomic frequency measurements. With the measurement process adopted in modern experiments the NR contribution to the 1s-2s transition energy can reach 10-2 Hz, while the experimental inaccuracy is quoted to be ±46 Hz.
