text: Yo, check it out now, I'm 'bout to break it down,
  Talkin' 'bout the influence of a double bond, profound.
  In the middle of a hydrocarbon chain so flexible,
  Let's see how it affects the melting, let me tell the tale.
  
  Zinc stearate and zinc oleate, we gonna compare,
  Study the melting behavior, see what's in the air.
  Infrared spectra, keep an eye on the scene,
  Look for features that define the hydrocarbon chain's theme.
  
  The global conformation, that's what we're after,
  The double bond steps in, causing some laughter.
  It decouples the thermal evolution, no doubt,
  Disorder in the chain segments, they're out and about.
  
  Each side of the double bond, they break apart,
  Melting happens independently, it's a work of art.
  Segments in the assembly, they do their own thing,
  Double bond's influence, it's got that swing.
  
  So there you have it, the rap's complete,
  The influence of a double bond, can't be beat.
  Melting behavior, hydrocarbon chains in play,
  Science and rap, combining in a special way.
