Acetone (C₃H₆O), synonym 2-propanone, is a powerful solvent the molecule of which has 32 electrons. The molecule has a polarizability of 7.04 × 10⁻⁴⁰ F m², a dipole moment of 2.88 D, and an ionization potential of 9.70 eV. The molecule has 24 vibrational modes (Shimanouchi, 1972) as shown in Table 112.1.

112.1 TOTAL SCATTERING CROSS SECTION

Measured total scattering cross sections are given by Kimura et al. (2000) and shown in Table 112.2. Figure 112.1 provides a graphical presentation. Highlights of the cross section are

1.There are two peaks, at 1.5 and 8.0 eV.

2.The 8.0 eV peak is attributed ...
