Practise predicting the number of signals in the carbon NMR spectrum of a simple organic molecule, use a table of chemical shifts to determine the expected positions of these signals on the spectrum, and deduce the number of equivalent carbons responsible for each signal.
"The simulations are brilliant reinforcing material, delivered at a good pitch with scope for elaboration and so clear and informative. Students could attempt them many times, and this really helped weaker students build their confidence."
