Water and vegetable oil magnitude spectra measured with 96 echoes, spectral resolution 0.1 ppm, and rBW 434 028 Hz (Gread 127.42 mT/m). Water line was placed at 4.7 ppm. Vegetable oil methylene (-CH2-)n, methyl CH3, and unsaturated olefinic -CH = CH- lines can be seen at 1.4, 0.9 and 5.4 ppm, respectively. Spectra were measured with (a) one echo train, interleaved (b) two, (c) three, and (d) four echo trains. The ghost peaks of water and fat (-CH2-)n lines are marked by *.
