In pure water T2 is long, about 3-4 seconds because water molecules move considerably faster than the Larmor frequency. Please enable it to take advantage of the complete set of features! protract adds to prolong implications of needlessness, vexation, or indefiniteness. Following a radiofrequency pulse, this form of relaxation occurs with the time constant T2, where T2 is the time it takes for the transverse magnetization vector to decay to 1/e or 37% of its initial magnitude.
