  The importance of non-perturbative Quantum Chromodynamics [QCD] parameters is
discussed in context to the predicting power for bottom meson masses and
isospin splitting. In the framework of heavy quark effective theory, the work
presented here focuses on the different allowed values of the two non
perturbative QCD parameters used in heavy quark effective theory formula and
using the best fitted parameter, masses of the excited bottom meson states in
JP=(1/2)+ doublet in strange as well as non-strange sector are calculated here.
The calculated masses are found to be matching well with experiments and other
phenomenological models. The mass and hyperfine splitting has also been
analyzed for both strange and non-strange heavy mesons with respect to spin and
flavor symmetries.
