In recent papers a number of authors have considered Borel probability measures mu in R-d such that the Hilbert space L-2(mu) has a Fourier basis (orthogonal) of complex exponentials. If mu satisfies this property, the set of frequencies in this set is called a spectrum for mu. Here we fix a spectrum, say G, and we study the possibilities for measures mu having G as spectrum.
