We consider in detail the mass operator analysis for the nonstrange (Formula presented) excited baryons in large (Formula presented) QCD. We present a straightforward procedure for constructing the large (Formula presented) baryon wave functions, and provide complete analytic expressions for the matrix elements of all the independent isosinglet mass operators. We discuss the relationship between the old-fashioned operator analyses based on nonrelativistic SU(6) symmetry and the modern large (Formula presented) approach, which has a firmer theoretical foundation. We then suggest a possible dynamical interpretation for the subset of operators preferred strongly by the data.
