WebSep 26, 2007 · A spherical top molecule is a special case of a symmetric tops with equal moment of inertia about all three axes IA = IB = IC. The spherical top molecules have cubic symmetry . Examples of spherical tops are: methane (CH 4 ), phosphorus tetramer (P 4 ), carbon tetrachloride (CCl 4 ), ammonium ion (NH 4+ ), and uranium hexafluoride (UF 6 ). WebJan 4, 2024 · The simplest possible effective Hamiltonian for the ground vibrational state is that of a rigid spherical top Hgr = B ″ J2 (1) where B ″ is the ground state rotational constant, which is inversely proportional to the moment of inertia.
