Material Science question 12 Which of the following is NOT a

Which of the following is NOT a technique associated with the identification of molecular structure in polymeric materials? (circle your answer) b.) For an FTIR spectrum where infrared radiation is absorbed by C = N bonds at a wavelength of lambda = 4.5 mu m, calculate the energy of these photons (circle best answer). Note: Planck constant h = 6.626 times 10^-34 J-s and speed of light c = 3 times 10^8 m/s. FTIR E = 12 times 10^-20J X-Ray diffraction E = 8.8 times 10^-20 J Rockwell Hardness E=4.4 times 10^-20 J TEM E = 12 times 10^-8 J

Solution

Rockwell Hardness.
