Table 1. Calculated binding sites and interaction energies between water and the L-type valinomycin monomers (M_L) on the Cu(111) surface. A more negative energy indicates that the calculated system is more stable.

M_L	Mode a	Mode b	Mode c	Mode d	Mode e
Binding sites	N(1)H	O = C − O(2); C = O(18)	C = O(3)	O = C − O(5)	C = O(1); C = O(4)
Interaction energy (kcal/mol)	−6.00	−12.57	−9.07	−7.44	−13.25

Note: The code number of the nitrogen or oxygen atoms is consistent with the structural formula of valinomycin in Figure 1a.
