Problem E12C.4(a)

The $${ }^{13} \mathrm{C}$$ NMR spectrum of ethanoic acid (acetic acid) shows a quartet centred at $$\delta=21$$ with a splitting of 130 Hz. When the same spectrum is recorded using proton decoupling, the multiplet collapses to a single line. Another quartet, but with a much smaller spacing, is also seen centred at $$\delta=178$$; this quartet collapses when decoupling is used. Explain these observations.
