We show that the recently proposed scaling laws [see G. Zhuang, W. Wang, Phys. Lett. A 268 (2000) 413] for chain diffusion on missing-row Pt(110) have no real meaning, since they cannot be extended outside the narrow chain-length range which has been considered by Zhuang and Wang. The only asymptotic scaling law gives a chain mobility which is inversely proportional to the chain length; however this asymptotic scaling behaviour is not physically important due to the occurrence of multiple upward promotions for long chains.

Abstract
We show that the recently proposed scaling laws [see G. Zhuang, W. Wang, Phys. Lett. A 268 (2000) 413] for chain diffusion on missing-row Pt(110) have no real meaning, since they cannot be extended outside the narrow chain-length range which has been considered by Zhuang and Wang. The only asymptotic scaling law gives a chain mobility which is inversely proportional to the chain length; however this asymptotic scaling behaviour is not physically important due to the occurrence of multiple upward promotions for long chains.
