  We consider effective theory treatment for the lowest-lying $S$- and $P$-wave
states of charmed mesons. In our analysis, quantum corrections and
contributions from leading chiral and heavy quark symmetry breakings are taken
into account. The heavy meson mass expressions have abundance parameters,
low-energy constants, in comparison to the measured charmed mesons masses. The
experimental and lattice QCD data on charmed meson spectroscopy are used to
extract, for the first time, the numerical values of the full set of low-energy
constants of the effective chiral Lagrangian. Our results on these parameters
can be used for applications on other properties of heavy-light meson systems.
