The possibility of enhancement of Raman intensity of atmospheric nitrogen and oxygen by amplification the electromagnetic field near the surface of a silver diffraction grating is demonstrated. The greatest coefficient of Raman intensity enhancement was about 8 times and was observed under conditions of propagating surface plasmon-polaritons excitation.
