The decay rates and spectroscopy of the D and Ds mesons are computed in a nonrelativistic phenomenological quark-antiquark potential of the type V(r)=-4/3(αs)/(r)+A rν with different choices of ν. Numerical method to solve the Schrödinger equation has been used to obtain the spectroscopy of qQ mesons. The spin hyperfine, spin-orbit and tensor components of the one gluon exchange interactions are employed to compute the spectroscopy of the excited S states, low lying P-waves and D-waves. The numerically obtained radial solutions are employed to obtain the decay constant and leptonic decay widths. It has been observed that predictions of the spectroscopy and the decay widths are consistent with other model predictions as well as with the known experimental values.
