Abstract :
A two-level quantum system is considered in which relaxation processes with characteristic time constants T1 and T2 are present. The shift in frequency due to perturbations at two different frequencies is calculated. The general result is experimentally verified for the 
transition of atomic hydrogen, when the frequency of the external perturbations is close to the unperturbed two-level transition frequency.
