VNL nanotube grower question

[serhan]

Hi all,

In Nanotube Grower, carbon nanotube period length is shown dependent on the indices and the C-C bond length. Which formula is used in this tool to calculate the period from the bond length? Could you please give the formula and a reference?

Thanks a lot,

Serhan
