B factor values for various deformations and materials.
The black-filled squares and red-filled circles are data of ethanol, while the blue- and green-filled triangles are that of ethanol-water 50:50 mixture. Numbers are the normalized size parameter X. The averaged B factor (black line) is clearly distinguished from the B factor for an ellipse (red line at B = 0.75) and that for a quadrupole (dotted line at B = 0). The fitting error is indicated as a shaded region. Inset: An example of the reconstructed profile. The experimental conditions are indicated in the text.
