Abstract: The mass spectrum of the D-wave K mesons is considered in the frame work of relativistic harmonic model (RHM). The full Hamiltonian used in the investigation has the Lorentz scalar plus a vector harmonic-oscillator potential, the confined-one-gluon-exchange potential (COGEP) and the instanton-induced quark-antiquark interaction (III). It is shown that the anti-symmetric spin orbit potential of the III contributes substantially to the mass difference between the 11D2 and 13D2 mesons in the K meson sector. A good description of the mass spectrum is obtained. The respective role of III and COGEP in the D-wave meson spectrum is discussed. PACS Nos. 14.40.-n; 14. 40. Aq; 14. 40. Ev; 12.39.-x; 12.39. Ki
