Abstract

Precise measurement of atomic transition frequencies (neutral, ion) have been performed and the uncertainty of the order of 10−18 has been attained with several transitions. However, the measurement uncertainty lower than 10−15 has never been attained with molecular transition frequencies. Precise measurement of molecular transition frequencies are useful to develop physics beyond the standard model: detection of electron electric dipole moment, detection of symmetry violation between optical isomers of chiral molecules, and search for the variation in the proton-to-electron mass ratio etc..
