Abstract

Abstract: Time-proportional-phase-increment (TPPI) techique is used to remove the radiation damping related harmonic peaks from two-dimensional correlation (COSY) and multiple-quantum (MQSY) spectra. In 2D experiments, the mixing ^c/2 pulse usually changes the phase of the water magnetization nonlinearly. The combination of this nonlinear phase change with radiation damping results in chemical-shift-offset dependent harmonic peaks. However, if the phase of the mixing pulse is proportional to the evolution time t₁, the harmonic peaks disappear completely while the water peak remains unchanged.

Key words: Radiation damping, TPPI, Harmonic peaks, COSY, MQSY
