A general treatment of hindered internal rotation is given for molecules that can be regarded
as a rigid symmetric top attached to a rigid frame which may be completely asymmetric. The …

IN typical collisional or spectroscopic experiments, molecules rotate freely with random
spatial orientations. The resulting isotropic averaging obscures or suppresses much …

That his Nobel lecture might be regarded as a tour through a family album is the view
expressed by DR Herschbach in a note of thanks to his co‐workers. The following citation might …

Empirical study of cubic and quartic vibrational force constants for diatomic molecules shows
them to be approximately exponential functions of internuclear distance. A family of curves …

The ground-state electronic energy of helium-like atoms is calculated by interpolating between
exact solutions for the limiting cases of one-dimensional and infinite-dimensional systems…

A semiclassical treatment of the photodissociation of a diatomic molecule is developed. It is
shown that the angular distribution of products will often be peaked parallel or perpendicular …

Effective diameters of atoms and molecules can typically be estimated within about 1% from
equation-of-state or compressibility data. These estimates correlate well with critical volumes…

The pressure and temperature dependent viscosities of two glass forming liquids, glycerol
and dibutyl phthalate (DBP), have been studied in the range P=0–3 GPa, T=0–125 C, and η=…

The distribution of velocity vectors of reaction products is discussed, with emphasis on the
restrictions imposed by the conservation laws. The recoil velocity which carries the products …

We present in situ observations of hydrocarbon formation via carbonate reduction at upper
mantle pressures and temperatures. Methane was formed from FeO, CaCO 3 -calcite, and …
