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.

Provide the 1H and 13C NMR data for thiophenol. Note the chemical shift, multiplicity, and integration for each (e.g. d 1.0, 3H, triplet). Clearly identify which proton is being reported and which carbon is being reported. Provide the 1H and 13C NMR data for the product generated in Question #1. Note the chemical shift, multiplicity, and integration for each (e.g. d 1.0, 3H, triplet). Clearly identify which proton is being reported and which carbon is being reported.
