Multiple quantum filters (MQF) and coherence order transfers. For triple quantum filter (TQF) with six-phase cycling, θ1 = θ2 = θ3 = 90°, φ1 = 30°, 90°, 150°, 210°, 270° and 300°, φ2 = φ1 + 90°, φ3 = 0°. For double quantum filter (DQF) with four-phase cycling, θ1 = θ2 = θ3 = 90°, φ1 = 0°, 90°, 180°, and 270°, φ2 = φ1, φ3 = 0°. For DQF with magic angle (DQF-MA), θ1 = 90°, θ2 = θ3 = 54.7°, and the phase cycling is the same as for DQF. For all filters, the receiver phase alternates between 0° and 180°.
