In this abstract we present a novel technique for chemical species separation using a signal model formulated entirely in k-space. The model includes T2* decay, field inhomogeneity and a variable time map. By using a variable time map this method is able to separate species without artifacts produced by chemical shift, field inhomogeneity or T2* decay.
