Solution: Which isn't true about  13C NMR spectroscopy? a. Each distinct carbon produces a single peak  13C  NMR spectrum. b. Splitting of signals into multiple peaks is not observed in routine  13C  NMR spectra. c. Decreased electron density around an atom shields the atom from the magnetic field d. Larger mass of samples is usually required. e. 13C  spectra are usually less complex and easier to interpret than 1H NMR
