Table 1. Parameters for the 3-12 Lennard-Jones surface potential.

Parameter	H	C	F	S	Co	Hg
A	2.26	3.43	2.68	4.22	1.86	3.05
B	2.46	2.98	2.69	3.18	2.33	2.59

Values of A are in Å(kcal/mol)^1/3, values of B are in Å(kcal/mol)^1/12, values of r are in Å, and those of V are in kcal/mol. The interaction between each atom and a gold surface is V = –(A/r)³ + (B/r)¹².
