Enhanced effect of temporal variation of the fine structure constant in diatomic molecules

Atomic Physics 2009-11-11 v3

Abstract

We show that the relative effect of variation of the fine structure constant in microwave transitions between very close and narrow rotational-hyperfine levels may be enhanced 2-3 orders of magnitude in diatomic molecules like LaS, LaO, LuS, YbF, etc. The enhancement is a result of cancellation between the hyperfine and rotational intervals.
