Figure 5.

Computed linear response theory IR spectra of hydroxide clusters shown earlier (a, left) between 1500 and 3200 cm⁻¹ and (b, right) between 3400 and 3800 cm ⁻¹. Color codes adopted here are the following: 3A0DS (black, labeled 3AS), 4A0DB (red, labeled 4AC), 4A0DS (dashed violet, labeled 4AS), 4A1DB (dotted blue), and finally 5A1DB (green). The spectra for the neutral water cluster are shown with black dashed lines. For clarity, the clusters contributing to the band between 1600 and 2500 cm⁻¹ are explicitly labeled as 3AS (3A0DS), 4AC (4A0DB), and 4AS (4A0DS). Reproduced from ref 55 with permission.
