Results of a photoemission study of the (100) surface of ZrN and NbN are reported. For the N 1s level a negative surface core level shift is identified on both surfaces. For the metal 3d levels a negative surface shift is determined on ZrN while that on NbN is found to be positive. Negative surface core level shifts are predicted for the metal 3d level in both cases using the thermochemical model. Upon oxygen exposures chemically shifted components appear both in the metal 3d and N Is spectra for both samples. From the shape of the N Is spectra it appears as if different N Is sites are created in the surface region upon oxygen exposures.
