The SU(2N{sub f}) x O(3) constituent quark model symmetry of the light diquark system are used to analyze single pion transitions of S-wave to S-wave and P-wave to S-wave heavy baryons. We show that the Heavy Quark Symmetry (HQS) coupling factors are given in terms of the three independent couplings g{sub {sigma}{sub Q}}{sub {lambda}{sub Q}}{sub {pi}}, f{sub {lambda}{sub Q}{sub 1}}{sub {sigma}{sub Q}}{sub {pi}} and f{sub {lambda}{sub Q}{sub 1}}{sub *{sigma}{sub Q}}{sub {pi}}. Light-Front quark model spin wave functions are, then, employed to calculate these couplings and to predict decay rates of single pion transitions between charm baryon states.
