Class Information
Number: 331/3
Name: Oscillators > Automatic frequency stabilization using a phase or frequency sensing means > Molecular resonance stabilization
Description: Subject matter wherein the frequency discriminator or sensing means is of the molecular or atomic resonance type, comprising a medium, which may be solid, liquid or gaseous, the frequency selective properties of which are due to the vibration or oscillation of the individual molecule or atom itself and are not due to the translational motion of the molecule or atom as a whole.
