Chemical shifts, in ppm, are independent of the magnetic field strength. T F b. In HNMR,...
Chemical shifts, in ppm, are independent of the magnetic field strength. T F In HNMR, spin-spin splitting is the only way to tell how many hydrogens of each type. T F An IR spectrum is a unique "fingerprint" of a molecule. TF In MS, the identification of oxygen in a molecule is the main goal. TF he reference standard called TMS is trimethylsilane.

provide structures for the spectral data provided Pages 1-5: provide the 5 structures for the spectral data provided. For full credit, you must be sure to assign/label all the NMR peaks and assign the major IR bands including those readily identifiable in the fingerprint region (use the IR spectral tables handed out in class). If you do not label anything on the spectra, you will lose most of the points for this problem set. Hint for the problems listed without...
