N1 localized Δρ(r)stat and Δρ(r) determined at (a) and (b) 200 K, and (c) and (d) 150 K, respectively. Δρ(r) is the Fourier transform of the GSF and IAM structure-factor differences, terminated at . All contours: 0.05 e Å-3; positive densities: continuous; negative densities: dotted; zero level: dashed. Map borders: 4.0 × 4.0 Å2. |
