Abstract

A molecule is usually classified according to the values of its principal moments of inertia. Following the most widely accepted convention for labelling the moments of inert i a I I I a b c or, alternatively, the rotational constants, A B C-i ii with A(cm ) = 2 etc., 8ir ci a a "spherical molecule" is a molecule possessing identical moments of inertia: I =1 =1 a b c A molecule may then be classified as "quasi spherical" if the principal moments of inertia are similar but not exactly equal. Two limiting cases may be identified: I I = I :prolate a b c I I <I :oblate a b c A few examples of both prolate and oblate "quasi spherical" symmetric tops are collected in the following Table.
