Deduce the structures of compounds given from the spectra provided assigning all 1H and 13C signals (1H on the front and 13C on the back). All spectra were taken in CDCl3. The peaks are designated as follows: s=singlet, bs=broad singlet, d=doublet, t=triplet, q=quartet, pent=pentet(quintet), sext=sextet, sept=septet, m=multiplet, d of d=double of doublet, etc. Draw the structure of each compound below the spectra. Label and assign all signals for both the 1H and 13C spectra. 2 3 5 6 g84884 te...

Consider the following, two-sided magnitude spectra for the signals g(t) and h(t). Write down the equations that you would use to construct g(t) and h(t) from the indicated spectra (you can assume that the phase spectra are zero in both cases). 1. abs(Dn) - Io Consider the following, two-sided magnitude spectra for the signals g(t) and h(t). Write down the equations that you would use to construct g(t) and h(t) from the indicated spectra (you can assume that the phase...
Label the significant peaks in the IR and NMR spectra. When analyzing the signals in the 'HNMR, be sure to include all appropriate information. For example: 3H, singlet, 0 neighbors, and c (the letter referring to the corresponding unique type of hydrogens that were labeled in the structure). It is recommended to provide more analysis for each signal than what is described above, when necessary, such as labeling any coupling constants if any are provided For NMR label each peak...
