Fourier transform infrared absorption spectroscopy and secondary ion mass spectroscopy have been carried out on GaAs based dilute nitride layers after treatment with H(+) or D(+) ions. Formation of N-H (D-H) centers is detected by vibrational absorption bands of H (D). The modes are assigned to two different complexes, each involving one H (D) atom. A major fraction of the hydrogen in the layers might be not or only loosely bound to nitrogen.
