The ratio of the absolute infrared intensity, A₃/A₂, for the
parallel mode (2336 cm⁻¹) and the perpendicular mode (658 cm⁻¹)
of a nonpolar solute molecule, carbon dioxide, has been determined
in a nonpolar solvent, Nujol. The solution ratio (5.0) which has
been extrapolated to zero concentration is less than the...
