[AMBER] What are Inner Sp2 carbons and non-pure aromatic systems?

Hi everyone,

In gaff.dat, there are some atom types being described as "Inner Sp2
carbons in conjugated systems" and "Sp2 N in pure aromatic systems"?

Does the former mean the two middle carbons as in C-C=C-C? And what
does "pure aromatic" really mean?

Thanks for any suggestion,
Yun
