Abstract

We consider the effect of α variation on the vibrational spectrum of Sr 2 in the context of a planned experiment to test the stability of μ m e/m p using optically trapped Sr 2 molecules. We find the prospective experiment to be 3 to 4 times less sensitive to fractional variation in α as it is to fractional variation in μ. Depending on the precision ultimately achieved by the experiment, this result may give justification for the neglect of α variation or, alternatively, may call for its explicit consideration in the interpretation of experimental results.
