A hierarchical procedure which automatically locates features in two dimen-<br />

sional NMR spectra based on <strong>th</strong>eir symmetry properties is described. The pro-<br />

cedure makes use of projection operators derived from group <strong>th</strong>eory. Results of<br />

<strong>th</strong>e procedure applied to COSY data for <strong>th</strong>e peptide hormone LHRH and barley<br />

subtilisin inhibitor protein are presented.
