    $\begingroup$ Which isomers of octane and nonane are you using? I'd expect the effect will depend on that. $\endgroup$

  • $\begingroup$ The difference between singular and plural - you said "isomers" $\endgroup$ Commented Jun 30, 2015 at 7:36
  • $\begingroup$ I can see someone else edited the question - could you please confirm you're asking about n-octane and n-nonane? Thanks. $\endgroup$
