Nuclear Magnetic Double Resonance: Systems of Two- and Three-Spin 12 Nuclei

Abstract

that the only terms retained in V are ones withj represented, = f dT[ 1: (X.X/Vi.XiX:+X.X/Vi.x/x.)]. J' evenThe second sum on the right evidently involves the ground-state permanent moment of the 11th molecule interacting with the rs transition moment of the jthmediated by the appropriate trigonometric factor. The corresponding reduction of (cpo' I V I CPu') is the same except that II is odd. The transition moment correction 23 23 The full first-order correction contains a sum over s as well as terms involving larger denominators. 19.7
