Problem of the week #2

The link below shows the aromatic region in the ¹H NMR spectrum of m-nitrophenol. There are four signals in this region. Draw the molecule out and label the aromatic H’s a-d. Then, describe this portion of the spectrum in a line list with chemical shift (d), multiplicity (e.g. ddd), and J-values (Hz). The exact shifts and J-values can be found in the drop-down menu to the left of the spectrum.
