Abstract: | A novel method of high-resolution spectroscopy of gases is proposed. The method is based on observing the optical behaviour of thin vapour layer when the particles cross the light beam or collide with the cell walls. The atomic motion and electronic quenching on gas-solid interfaces are explored by numerical analysis. The periodicity of peak values of transmission spectra and its derivative spectra demonstrates a sub-Doppler structure corresponding to the resonant transitions. |
