Abstract :
The measurement of the frequency difference of rovibrational transitions from two different molecules is suggested to test the variation of the electron-to-proton mass-ratio μ. The frequency of rovibrational transitions is sensitive to μ. Small frequency splittings reached between the transitions from two isotopomers allow an enhancement relative to the variation of μ.
