Line profile density variation

Fig. 3.29. Onset of ternary (H2-Ar-Ar) interactions the variation of fitted profiles of the H2 So lines with density argon with 3% hydrogen admixture. Solid line zero density limit (profile of H2-Ar) dashed line at 185 amagat of argon where ternary interactions have affected the profile. The functions are scaled so that the areas under the curves are equal after [152],...

Figure 4.30 (a) Evolution of local current density profile upon variation of the total current J (indicated) in the cell. Solid lines—anal3dical solution (4.243) of reduced system, and dashed lines—numerical solution of the full system of equations (4.197), (4.198) and (4.233). Parameters are = 1, A = 100, = 8, p = 1, and 7 = 2. The other parameters required... 

Similar results were also obtained for argon-krypton mixtures [252]. Apart from the low-frequency region of the intercollisional dip, the variation of the translational line shape is rather subtle reduced absorption profiles of a number of rare gas mixtures at near-liquid densities (up to 750 amagat) have been proposed which ignore these variations totally [252],... 

In general, the hollow cylinder or average microenvironment model fits the NH data extraordinarily well with only minor variation in rj, the effective density of animals. The required variation in r- presumably comes about because of the uneven distribution of animals within sediment (Jumars et al., 1977) and mobility. It may also be apparent variation due to the arbitrary requirement that r, remain fixed. The variation forced into r2 by this restriction could actually reflect changing boundary conditions at r, for example, inhibition to diffusion by burrow linings or a reduction in irrigation activity. A part of the discrepancy between the model and measured profiles could also reflect changes in the production rate of NH/ because of factors other than temperature. For example, fall profiles may show a smaller maximum than predicted, due to a lower reaction rate resulting from a depletion of substrate (see Nixon et al., 1980). 

Fig. 3.26 Determination of density profiles of H2 molecules in a flame. R is the distance from the burner axis, z the distance along this axis. The profiles in (a) have been obtained from the spatial variations of the Q line intensities and spectral profiles shown in (b). The relative intensities of Q J) furthermore allow the determinations of the temperature profiles. The numbers with the horizontal lines give the expected signal heights fot the labeled temperatures T in [K] [348]...

Fig. 16 Data profiles obtained from contrast variation using five different decane contrasts for the diblock 5DH8HH at = 2% and room temperature. The solid lines display the fit prediction using a smeared step function for the brush profile. The scattering lengths densities of decane corresponding to the different curves are 6.2 x 10 ...
