The spectrum from Model 1 is reproduced below. Recall that a cluster with one peak is called a singlet, two peaks = doublet, three peaks = triplet, and four peaks = quartet. Any cluster with five or more peaks will be called a multiplet. Label peak clusters a and b, below, with singlet (s), doublet (d), triplet (t), quartet (q), or multiplet (m), as appropriate
