We
  present density matrix calculations of the carbon spectra of doubly labelled
  hyperpolarized [1, 2 -13C2] pyruvate at 3.0 tesla, showing the combined
  effects of hyperpolarization and strong scalar coupling upon the asymmetry of
  the multiplet lineshapes. The
  possibility is discussed of using the asymmetry to measure hyperpolarization
  in situ. The importance of multi-spin
  order in causing the asymmetry is discussed.
