Table 2. Included in this table are the plasma frequency ν_p and the damping frequency γ for the Drude model, the measured contact angle θ and the non-retarded Hamaker constant H between liquid II and the following metallic substrates immersed in liquid I: gold, platinum, silver, aluminium.

Material	ν_p (10 ¹⁵ s ⁻¹ )	γ (10 ¹² s ⁻¹ )	θ (°)	H (10 ⁻²² J)
Gold	2.183	6.46	62±3	18.2
Platinum	1.244	16.73	76±4	5.97
Silver	2.18	4.353	76±3	18.1
Aluminium	3.57	19.79	NW	30.3

Here NW stands for non-wetting.

θ is the angle between the solid surface and the surface of liquid II.
