A study of the spectroscopy and decay properties of the B and mesons is carried out within the framework of the phenomenological quark-antiquark potential model using the Hydrogenic and the Gaussian wave function. The spin-hyperfine, spin-orbit and the tensor interactions are employed to obtain the pseudoscalar and vector meson masses incorporating the effect of mixing. The decay constants are computed using the wave function at the origin. The leptonic branching fractions, electromagnetic transition rates and mixing parameters of the B and are also calculated in this scheme. Our predictions are in good agreement with the experimental results as well as the lattice and other theoretical models.
