We study how moderate rotation affects photometric observables in ß Cephei stars. The most important effect is the rotational mode coupling of modes with harmonic degree, l, differing by 2 and the same azimuthal order, m, if the frequencies are close. This is not an uncommon situation among unstable modes in ß Cep stars. Positions of the coupled modes in the amplitude ratio vs. phase difference diagrams are aspect, i, - and m-dependent. Inference from the diagrams becomes more complicated.
