抒情短诗

Fourier Techniques in X-Ray Structure Determination,s, it is necessary to have the phases of the structure factors for a Fourier synthesis to be carried out meaningfully. One way in which phase information may be obtained is through the Patterson function of vector density, a function of interatomic vectors in the crystal structure.

Intend

Neutron Diffraction from Single Crystals,ising from the unpaired electrons, give rise to the . structure shown in Fig. 11.1b. The magnetic moment of the neutron interacts with the permanent dipole of chromium to form this structure, and consequently the diffraction record shows a primitive cubic structure.

However, in structure determinations with modern equipment, it is not uncommon nowadays to by-pass this step and proceed immediately with X-ray studies. This is because in most cases, the X-ray technique is straightforward and test data can be quickly scanned with a single-crys

Fourier Techniques in X-Ray Structure Determination, the 1920s with very simple and highly symmetrical structures, it was found that the application of Fourier series, initially in one dimension, led to the electron density function, in which peak maxima in the electron density corresponded to atomic positions. As we have seen in the previous chapter

We would also remind readers that although there are definite distinctions between large and small molecules in the crystallographic arena, there is no reason to exclude one from the other, and in fact, there are many

Neutron Diffraction from Single Crystals, a neutron beam. As an example, when the structure of elemental chromium is examined by X-ray diffraction, it shows a body-centered cubic arrangement, Fig. 11.1a. Elemental chromium has the electronic configuration (Ar 3d. 4s.); it is antiferromagnetic at room temperature, and its electron spins, ar
