In this article we give a review of certain aspects of the present understanding of spectroscopy of heavy mesons and constituent quark masses in the light of non‐relativistic potential model approach motivated by quantum chromodynamics. We find that the one gluon exchange at short distance and colour‐confining interaction at large distance which is pure scalar (or scalarvector admixture with dominant scalar interaction) under the Lorentz transformation, can explain only partially the present data on 1 P states of b b and b b states. The S ‐wave data, that are available at present, however can be understood with both scalar confinement or scalar‐vector admixture with scalar‐dominant interaction.
