Report Please submit your report as a single Microsoft Word or pdf file. It should include: a) a table of observations for the standards and unknowns from the burning experiments. Identify your unknowns using the results of your heating and burning solubility tests; b) your infrared spectra (scan or take a photo with your phone and insert each spectrum into the Word document). Interpret the infrared spectra of the unknowns to confirm the deductions from the other tests. The following points may be helpful: IR spectra of some common polymers may be found on pages 8-13, and on a range of web pages. You can identify a polymer by comparing the unknown and known spectra, taking account of the overall shape of the spectrum - the number and relative intensities of the bands and the energies (wavenumber in cm¹; equal to the inverse of the wavelength) of the major bands. You do not need to identify all of the bands in the spectra, although some may be assigned to particular types of molecular vibration; e.g. C-H stretches near 3000 cm-¹. Remember that some polymers may be blends, or be compounded with other materials, and this may cause extra bands in the spectra. Important: Please explain the reasoning behind your identification of each unknown polymer. Remember to specify what each unknown was used for.
