Differential polarizability spectra. a Differential dynamic polarizability Δα(λ) for Θ = π/2 (red dots) and Θ = 0 (blue dots). b Corresponding scalar Δαs(λ) (green dots) and tensor Δαt(λ) (magenta dots) parts. The magenta cross is Δαt(λm) determined from measurements in Fig. 3b. The solid and dotted curves are calculations based on Models 1 and 2, respectively (see Methods section). Error bars represent 1 s.d. of the measured polarizability values
