The Light hadronic decay and decay rates of mesons (QQ-bar) are studied in the NRQCD formalism in terms of their short distance and long distance coefficients. The long distance coefficients are obtained through phenomenological potential model description of the mesons. The mass spectrum of the and mesons are reviewed in non-relativistic phenomenological quark antiquark potential of the type V(r) = -({alpha}{sub c}/r)+Ar{sup {nu}}, with {nu} varying from 0.5 to 2. The digamma and quarkonia decays into light hadrons are investigated by incorporating the relativistic corrections of order v{sup 4} within the NRQCD formalism.
