Second-order Derivatives and Rearrangements

Inequality (1.2) is classical and very well known. It has been the object of extensions and variants which can be found in a number of papers and monographs, including [AFLT], [Bae], [BBMP], [BH], [Bro], [BZ], [CP], [E], [H], [Ka2], [Kl], [Ma], [Sp1], [Sp2], [Spi], [Ta1], [Ta5], and [Ta6]. Even if not as popular as (1.2), inequality (1.1) has also been known for a long time, and versions of it ...

General Physics I. Molecular Beams

1. Introduction Since the first measurements of the velocity distribution of atoms evaporating from the surface of bulk liquid helium by Johnston and King, several theories have been advanced to explain the helium evaporation process. In these theories, the excita-tions in liquid He II, phonons and rotons, play an important role in the evaporation mechanism. In this report, we discuss an experi...

Molecular rearrangements of superelectrophiles

Superelectrophiles are multiply charged cationic species (dications, trications, etc.) which are characterized by their reactions with weak nucleophiles. These reactive intermediates may also undergo a wide variety of rearrangement-type reactions. Superelectrophilic rearrangements are often driven by charge-charge repulsive effects, as these densely charged ions react so as to maximize the dist...
