A key step in interpreting NMR data is in counting correctly the number of signals associated to the compound of interest. This puzzle covers one particular example.
For a pure unknown compound, the 13C NMR spectrum below shows several 13C signals at varying intensities. What is the minimum C atom count?
4 Carbons (including a CF3-Group, splitting into a quartet).
