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