Abstract : A krypton sensitized mixture of the two stable molecules 14N2 and 15N2 was irradiated with the two krypton resonance wave lengths Lambda-1 = 1165A and Lambda-2 = 1236A. The experiments showed that an amount of the mixed molecule 14N15N was formed increasing with illumination time. It was concluded that the photochemical dissociation of nitrogen molecules is possible, and that the dissociation energy is smaller than the shorter wave length Lambda-1 corresponding to 10,64 ev. The possibility that the mixed molecules were formed by collision of excited molecules cannot be excluded. Results of the experiments with the nitrogen isotopes are used to explain why the mass spectrometric detection of N2H4 was unsuccessful.
