Abstract

Abstract The theoretical basis for the use of cross correlation to extract an undistorted spectrum from a rapid scan response (as first suggested by Dadok) is examined in detail. It is shown that the desired information can be obtained either by cross correlating the rapid scan responses of the unknown and a reference consisting of only a single sharp NMR line or alternatively by applying to the Fourier transformed response an appropriate analytical function. Practical considerations in the use of rapid scan FT-NMR are explored, and illustrative examples are given. The method compares favorably with pulse FT methods in sensitivity and, in some instances, has distinct advantages over the pulse technique.
