Frequency-modulated (FM) pulses that function according to adiabatic principles are
becoming increasingly popular in many areas of NMR. Often adiabatic pulses can extend
experimental capabilities and minimize annoying experimental imperfections. Here,
adiabatic principles and some of the current methods used to create these pulses are
considered. The classical adiabatic rapid passage, which is a fundamental element upon
which all adiabatic pulses and sequences are based, is analyzed using vector models in …
