Conclusions
In the experimental study of S-signals, two-frequency four-pulse programs with time division offer substantial advantages over three-pulse programs and a program using four pairwise-acting RF pulses, the first in which S-signals were detected. It is also of no little importance that the study of programs with time division indicates the necessity of allowing for the entire set of phase relationships formed under a multipulse multifrequency input in the description of spin-system behavior.
