Exercise 15: X-ray diffraction by a row of identical atoms Consider the linear chain of carbon atoms shown in Fig. 13. This structure could easily be a chain of hydrocarbons with alternating single and double bonds such as -C-C-C-C-C-C-C=. (0) (1) (2) (3) Figure 13 (4) (5) Wy (1) (0) y (2) (3) Figure 14 (a) What is the lattice vector? What is the basis? Specify using the a conventional notation with b==. 4 (b) Monochromatic X-rays of wavelength 2 illuminate the chain. (i) Evaluate the path difference between the waves diffused in the angle 8 by the atom positioned at the origin (0) and the atom placed in position (2). Indicate the possible values of (or of one of its trigonometric function) observed by diffraction assuming that the chain consists only of atom pairs (crystal diffraction). Show that the addition of odd atoms accentuates the diffracted intensity in certain directions while diminishing it in others (always assuming that b==). Find the result using the structure 4 factor. a TU (ii) Numerical application: A = 0.5 Å, a = 0.5 Å, determine the table of increasing values from 0, 0≤0≤, for which 2 the diffraction conditions are satisfied. State the values
