The embodiment of the application relates to a molecular clock with delay compensation. A clock generator (100) includes a hermetically sealed cavity (102) and clock generation circuitry (106). A dipolar molecule (104) in the hermetically sealed cavity (102) has a quantum rotational state transition at a fixed frequency. The clock generation circuitry (106) generates an output clock signal based on the fixed frequency of the dipolar molecule (104). The clock generation circuitry (106) includes a detection circuit (119), a reference oscillator (108), and control circuitry (124). The detection circuit (119) generates a first detection signal and a second detection signal representative of amplitude of signal at an output of the hermetically sealed cavity (102) responsive to a first sweep signal and a second sweep signal input to the hermetically sealed cavity (102). The control circuitry (124) sets a frequency of the reference oscillator (108) based on a difference in time of identification of the fixed frequen
