text: Yo, check it out, I'm 'bout to drop some knowledge,
  Investigating the molecular ortho-hydrogen inside C60, I acknowledge.
  Using inelastic neutron scattering, I'm the master,
  Unveiling the rotational ground state, causing a disaster.
  
  Temperature down to 60 mK, we go,
  Studying the INS line, let it flow.
  Transitions between sub-levels, ortho to para,
  I'm a lyrical scholar, dropping knowledge like a mantra.
  
  At ambient pressure, ortho sub-levels split,
  Low energy non-degenerate, high energy double hit.
  Separated by 0.135 ± 0.010 meV, that's the game,
  Hydrogen molecules in axial symmetry, ain't it insane?
  
  Icosahedral symmetry of C60 cages, they take a backseat,
  In the solid phase, axial symmetry's what we meet.
  Inter-cage interactions, they play a role,
  Determining the symmetry breaking potential, that's the goal.
  
  Hydrostatic pressure, let's turn up the heat,
  Investigating the fine structure, can't be beat.
  The INS spectra reveal the potential's sway,
  Neighbouring cages dictate the H2 energy display.
  
  Low-temperature crystalline phase of C60, it's a sight,
  Symmetry breaking, shining bright in the night.
  So remember this rap, it's a scientific creation,
  Ortho-hydrogen in C60, a fascinating revelation.
