For the graphs provided, I need an analysis. These graphs are from a lab where we tested 3 shoes to determine the Co-Polymer Composition (ethylene vinylacetate) (EVA). The SAMPLES we tested are the graphs labeled “Hello Kitty”, “Toy Story”, and “Pink New Balance” The STANDARDS are labeled “AT1231”, “AT1821” and “SA340502”
Standard 1 (AT1231): Nominal wt% vinyl acetate- 12%
Standard 2 (AT1821): Nominal wt% vinyl acetate- 18%
Standard 3 (SA340502): Nominal wt% vinyl acetate- 40%
Questions to answer: Which band(s) in the IR spectrum did you use to determine the ethylene content of the co-polymer? Which band(s) did you use to determine the vinyl acetate content? To which functional groups and vibrational modes do these bands correspond?
For the standards, how do the absorbance intensities change as the composition changes?
Are these changes consistent with compositional changes? Explain
Is it possible to distinguish between the three insoles with only ATR-IR?
Is this technique suitable for routine forensic analysis of copolymer samples? Justify your answer.
Please include the major peaks for EACH IR. The functional groups that can be seen in the IR, and the absorbance changes with composition for the STANDARDS. PLEASE ANSWER THESE QUESTIONS IN SENTENCE FORMAT
