Water suppression pulse schemes utilized for the 2D [1H, 1H] NOESY experiments. (A) The 3–9-19 sequence with total durations of 3.02 ms and 2.4ms for interpulse delays of 200 μs and 75 μs, respectively. (B) The WATERGATE sequence with a total duration of 6.04 ms using a selective pulse of 2 ms. (C) The WATERGATE sequence with water flip-back pulses for a total duration of 8.03 ms. (D) The excitation sculpting sequence with a total duration of 8.04ms. (E) The WADE sequence with a maximum RF amplitude of 5 kHz and a total duration of 5.01 ms. Unfilled wide and narrow rectangular shapes represent hard π and π /2 pulses, respectively. Unfilled shapes in 1H channel represent water-selective π/2 or π pulses. Filled shapes represent gradient pulses of 1 ms duration.
