and H-NMR – label both unambiguously and clearly illustrate that
you understand proton and carbon environments (i.e. Draw out the
skeletal structure of the compound, label the H’s a, b, c’s and the
C’s 1, 2, 3’s. Then label all signals on the NMR with those
corresponding letters/numbers accordingly.).

The following slides contain 1H and 13C-NMR spectra as well as
GC/MS spectra for compound 2 shown below. After analyzing the
spectra, assign all proton and carbon NMR signals using the
numbering given on the structure. Additionally, present your data
in table form including chemical shift, integration, coupling
pattern, and coupling constants (where possible). For mass spectral
data, justify key fragmentations (those which are starred*) by
proposing fragment structures.
