Molar polarizability number average

McCullough, E. A., Jr., / Chem. Phys., 63, 5050, 1975. This calculation is for the parallel component, not the average polarizability. Maryott, A. A., and Buckley, R, U. S. National Bureau of Standards Circular No. S37, 1953. A tabulation of dipole moments, dielectric constants, and molar refractions measured between 1910 and 1952, and used here to determine polarizabilities if no more recent result exists. The polarizability is 3/(47tNJ times the molar polarization or molar refraction, where is Avogadro s number. The value 3/(47tN ) = 0.3964308 x 10" cm was used for this conversion. A dagger (t) following the reference number in the tables indicates that the polarizability was derived from the molar refraction and hence may not include some low-frequency contributions to the static polarizability these static polarizabilities are therefore low by 1 to 30%.
