X‐ray emission and absorption spectra of carbon nitride films prepared by laser ablation were measured. The carbon x‐ray spectra of films obtained in a nitrogen atmosphere were different from those of a film prepared in vacuum. It was found from DV‐X α molecular orbital calculations on x‐ray spectra that the films obtained in a nitrogen atmosphere contained bonding between carbon and nitrogen atoms. This was supported by the Fourier transform IR spectra. Copyright © 1999 John Wiley & Sons, Ltd.
