(and is hence also equal to 1 for spherical molecules).

The photographs, made with scanning electron microscopes, clearly show the spherical molecules, packed together like so many ball bearings, on sheets of gold foil.

The first was proposed by Smalley, who believes that the spherical molecule is produced by the growth of open sheets of pentagons and hexagons.

The chemists found a way to hook these phenylacetylene units together in branching patterns that finally converge into a roughly spherical molecule.

The helium atoms are too large to leak through the spaces between carbon atoms in the spherical molecules and are permanently trapped.

The model depicts an attack by spherical molecules of the H.I.V. organism.

The polarizability ellipsoid of spherical top molecules is in fact spherical so those molecules show no rotational Raman spectrum.

In linear and spherical top molecules rotational lines are found as simple progressions at both higher and lower frequencies relative to the pure vibration frequency.

Most of these roughly spherical molecules consisted of arrays of 60 atoms in the form of truncated icosahedrons, having 12 hexagonal surfaces and 12 pentagonal surfaces.

Carbon atoms link together and form a faceted spherical molecule around a single metal atom.
