Tensor evaluations of biological polymers are usually bisphthalimide compounds. The 15 N CSA tensor elements (d 11 , based on labeled-model-compound studies; thus, a series of d 22 , and d 33 ) for the labeled derivatives were determined from CSA labeled model imide compounds based on the phthalimid
