Yes, I think your idea will work. All aromatic bonds have to have adjacent aromatic bonds. So if you find an adjacent aromatic bond, that should tell you the inside of the ring.
The only problem you might run into is if you have two adjacent aromatic rings how can the bond common to the two rings be rendered? Then you might want to consider placing a dashed line on both sides of the bond. -Tom ----- Original Message ----- From: "Miguel Howard" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Cc: <[EMAIL PROTECTED]> Sent: Friday, December 12, 2003 12:07 PM Subject: Re: [Jmol-users] aromatic bonds > Tom, > > Thanks for the .mol file that contains aromatic bonds. > > > At the bottom of the .mol file you will see a > > listing like this. > > The first two colomns are the atom numbers.
