From: Structural Stability and Deformation of Solvated Sm@C2(42)-C90 under High Pressure

(a) Frequencies of IR-active vibrational modes at 709, 640, (b) 724, 674, (c) 1472 and 1289 cm−1 for pristine (black square) and solvated (red triangle) Sm@C90 as a function of pressure. (d) IR-active vibrational modes of solvent (m-xylene) at 688 and 769 cm−1 as a function of pressure. (e) The C-C/C = C radial bending vibrations and (f) the C-C/C = C tangential stretching vibrations of solvated Sm@C90 as functions of pressure. The pressure coefficients are shown near the fitted lines.
