Scattering Method

It is seen that the values of the characteristic ratio estimated by the Stodc-mayer-Fixman method scatter about the Brant-Flory value, tending to increase systematically with monomer molar weight This trend is not in accord with the theoretical prediction (96, 97) that the characteristic ratios of polypeptides having side-chains longer than that of polyalanine should become constant. We... [Pg.117]

The structure was solved by Fourier and least-squares methods. Scattering factors for neutral Xe, Se, O, and F were taken from Doyle... [Pg.219]

Protein structures are now more often determined by using multiple anomalous dispersion (MAD) techniques. In this method, scattering that does not obey the kinematic theory is used. The kinematic theory deals with single scatter-... [Pg.147]

From the Prefaces to the Preceding Volumes New methods for the synthesis of organic compounds, improvements of known methods, and also old proved methods scattered in periodicals, are being recorded continuously in this book series. [Pg.286]

Despite some important structural information deduced from spectroscopic methods scattering techniques, theoretical and computational methods are necessary to analyse the complex molecular forces between the ions and interpret the experimental data. Increasing computer power will enable the refinement of the systems studied, bring the models closer to real systems [6]. [Pg.1121]

Full exploitation of this advantage can be obtained by the deuteration method. Scattering lengths for hydrogen and deuterium are widely different, so introduction of deuterium labels into the analyte will greatly increase the contrast. In order to perform the same contrast enhancement with X-rays, heavy atoms must be introduced, with the risk of unacceptable modifications of the sample morphology. Deuterium labelling is much less invasive under this... [Pg.540]

In 1975, the U.S. EPA had a set of six different samples analyzed by a number of laboratories using both the gravimetric and IR methods. Scatter in reported analysis included sampling errors as well as... [Pg.279]
