Diffusion weighed SE sequence with Stejskal-Tanner (A), Bipolar (B) and asymmetric bipolar (C) diffusion weighted gradients together with their gradient moments M_n(t) (Red: M₀; Green: M₁; Blue: M₂). D) The timing of the asymmetric Bipolar gradient waveform. Its first and second order gradients moments are zero when δ₁ = (-Δ δ₂ +δ₂ ε)/(Δ + 2δ₂ + ε).
