Abstract
Among topological descriptors topological indices are very important and they have a prominent role in chemistry. One of
them is atom - bond connectivity (ABC) index defined as
d ( ) d ( ) 2
( )
d ( )d ( )
G G
uv E
G G
u v
ABC G
u v
, where G d (u ) denotes
degree of vertex u. In this paper we compute this new topological index for V – phenylenic nanotube.
