The second example in the center panel shows the formation of a degenerate pair of Kubo components (i.e. having the same time constant). Plots of VIFs shown in Videos S3 and S5 are perfect examples of multicollinearity when a degenerate pair align. When a degenerate pair align (τ 1 ≈ τ 2 ), the FFCF reduces to Δ 1 2 exp(-t
