a Rotational constants from fit to data in [62021] and [73001].
 
b From fit to all data on 133Cs79Br and 133Cs81Br using the isotope relations for all other Dunham coefficients.  The remaining rotational constants were calculated by the isotope relations from 133Cs79Br.
 
c From ration Q(79Br) / Q(81Br) = 1.1970568(15). See [68003] and [66005] and eQq values in [72001].
