Calculation of line-shapes for systems undergoing chemical exchange and relaxation in magnetic resonance spectra

Abstract

An Algol-60 procedure and a FortranIV subroutine for the inversion of a complex matrix are given. These are applicable in the complete line-shape technique for studying chemical exchange and relaxation phenomena in n.m.r. and e.s.r. spectra. As an example the computation of the quadrupole broadening of the n.m.r. spectrum of a nucleus of spin ½ coupled to a nucleus of spin is considered.
