A novel approach to inversion recovery in NMR is described which combines adiabatic inversion with the observation of a spin echo refocused by a chirp pulse. This echo method allows one to generate in-phase magnetization over a broad range of frequencies. The effects are discussed of longitudinal and transverse relaxation during the pulse sequence, and the implications of scalar coupling are also investigated. [on SciFinder (R)]
