4. Analyze the IR spectrum of your product, filling in the table below. You should utilize your course textbook (pp. 764-766), if you need assistance. Please note that the frequency given below should be exact (one number), not a range. Use the frequency of the center of the band at its strongest point. Then, on the spectrum itself, mark the characteristic bands at their strongest point with a...
