On the adsorption of gases. Section I. Experimental methods. Introductory paper to section I

The theoretical aspects and importance of this reaction have already been discussed in the introductory paper of this series (part IV) as have also the experimental methods in broad outline. It will be assumed here that the reader is familiar with the paper. In the present paper will be found the experimental results of the tests suggested in part IV, together with an account of the effect of pn and temperature on the rate of combination of carbon monoxide with reduced hæmoglobin. It will be useful to describe first of all the results of a typical experiment at pH 10, temperature 21º C, [CO] = 0·1 mM, [Hb] = 0·06m M. These are plotted in fig. 1. It will be seen that the reaction is half complete in about 0·05 second and there is therefore no doubt that the apparatus is amply adequate for coping with the reaction, since in our previous papers we have shown that even reactions more than ten times as fast could still be accurately measured.

Definition Of

1. The definition of “normal” stars in spectral classification changes with time; at the time of the publication of theYerkes Spectral Atlasthe term “normal” was applied to stars whose spectra could be fitted smoothly into a two-dimensional array. Thus, at that time, weak-lined spectra (RR Lyrae and HD 140283) would have been considered peculiar. At the present time we would tend to classify such spectra as “normal”—in a more complicated classification scheme which would have a parameter varying with metallic-line intensity within a specific spectral subdivision.

Inelastic Processes

In this introductory paper, my primary concern will be in identifying and outlining the various types of inelastic processes resulting from the interaction of electrons with matter. Elastic processes are understood reasonably well at the present experimental level and can be regarded as giving information on spatial arrangements. We need not consider them here. Inelastic processes do contain information of considerable value which reflect the electronic and chemical structure of the sample. In combination with the spatial resolution of the electron microscope, a unique probe of materials is finally emerging (Hillier 1943, Watanabe 1955, Castaing and Henri 1962, Crewe 1966, Wittry, Ferrier and Cosslett 1969, Isaacson and Johnson 1975, Egerton, Rossouw and Whelan 1976, Kokubo and Iwatsuki 1976, Colliex, Cosslett, Leapman and Trebbia 1977). We first review some scattering terminology by way of background and to identify some of the more interesting and significant features of energy loss electrons and then go on to discuss examples of studies of the type of phenomena encountered. Finally we will comment on some of the experimental factors encountered.
