Spectroscopy Homework This packet contains 27 problems. Your assignment is to solve 8 of these. - Problems 1-6 (parts A, B and C): Do either all the A problems, or all the problems, or all the problems, as assigned by your instructor - Problems 7-15: Do any TWO of these problems Tum in only the pages for the problems you choose to do, and make sure your name is on each page Staple all the pages together in order Each problem contains the formula of the compound, the IR spectrum (% transmission vs. wavenumber, cm), and the 'H NMR spectrum (axis - chemical shift, ppm). Some spectra show a peak hovering above the baseline. This is an expanded view of one of the peaks to allow you to see splitting patterns more clearly TH This peak is a magnified version of this peak 3.0 2.1 25 2.4 For each problem, you must Calculate the degree of unsaturation - Assign IR absorption bands above 1500 cm - Draw the structure of the compound - Label the protons in your structure with letters and assign them to peaks in the NMR spectrum as we did in the examples in class (lab) 5C: CH0 2222 yu MC 1977 40 PE eta 10 val 000 OSE 1 100 HE HZ HZ
