Dicke narrowing
WebResults of the experimental study of the pressure dependence of self-broadening and shift of six isolated CO2 absorption lines in the 1.6-μm spectral range at room temperature are presented. The measurements were carried out at a high-sensitivity high-resolution diode laser spectrometer with a signal-to-noise ratio of 3000 to 7000. To … WebJun 4, 1998 · Dicke effect Scattering matrix Collision theories ABSTRACT The generalized Hess method (GHM) gives a line shape expression which is formally equivalent to the Rautian–Sobel’man hard collision model of Dicke narrowing, but differs radically in the definition of one of the relaxation terms.
