Extended Data Fig. 3: Angular radial distribution functions of solvent molecules closest to SWCNT surface.
From: Intermediate-range solvent templating and counterion behaviour at charged carbon nanotube surfaces

Distribution of orientations of the angle between amide dipole vector and vector pointing towards the nanotube central axis for NMP (a) and DMAc (b). Distances from SWCNT surface provide in 1 Å bins within the first solvation shell, showing how ~90° orientation of solvents (that is, dipole parallel to nanotube axis) occurs for the closest solvent molecules, while further molecules within the first solvation shell (4- 6 Å) have dipoles directed towards the nanotube (<90°).
