MOLECULAR BEAM MEASUREMENT OF THE ELECTRIC DIPOLE MOMENT OF KOH

Abstract

A molecular beam spectrometer has been used to determine the electric diple moment of the KOH molecule. This EDM had never been measured previously, although theoretical calculations had been made. A refined lineshape fitting procedure has helped make possible this determination from the molecular beam hyperfine spectrum. The value of the EDM which we found for the ground vibrational state is $7.386\pm 0.001$ debye.
