JAN RYDBERG, in Radiochemistry and Nuclear Chemistry (Third Edition), 2002 7.5 Inorganic nonmetallic compounds The time for a high energy particle to pass by an atom is ≤ 10−16 s. In this time the atom may become excited and/or ionized, but it does not change position (the Franck-...
Following the development of versatile laboratory measurement techniques, a number of these reactions were found to be fast, implying that the adiabatic principle was generally inapplicable to thermal energy ion–molecule reactions. Examples of rare exceptions are shown. More recently, there have been ...
Possible improvements of the interaction energy calculated using minimal basis sets Interaction energies for H 2 O·H 2 O, H 2 O·F and H 2 O·CH 4 have been calculated using the LCAO MO SCF method with minimal basis sets, and employing... W Ko?Os - 《Theoretical Chemistry Accounts》...
Chemistry: Mixtures of Liquids/Solutions/Composition, Molar Refractivity Again, this is a big industrial application area with the Abbe refractometer being extensively utilized. The Lorentz–Lorenz equation defines a term known as the molecularrefractivityor molar refraction, [R]: ...
A free-energy principle has been proposed recently that accounts for action, perception and learning. This Review looks at some key brain theories in the biological (for example, neural Darwinism) and physical (for example, information theory and optimal control theory) sciences from the free-energ...
NS Bayliss,EG Mcrae - 《Journal of Physical Chemistry》 被引量: 586发表: 1954年 Role of Kinetic Energy in the Franck–Condon Principle During an electronic transition in a molecule the nuclear positions and momenta (hence kinetic energies) both tend to remain fixed according to the Franck .....
Free energy: a user’s guide Article Open access 20 July 2022 1 Introduction There are countless complex dynamical systems in the universe. Some of them present an astonishing degree of complexity and an archetypal example of this is the human brain. Unfortunately, it is well-known that no ...

Doping can usually introduce impurity energy levels between the CB and VB, so that the band gap of the semiconductor can be reduced and the light absorption range can be enlarged, thereby improving the density of charge carriers. Show abstract Effects of surface wettability on (001)-WO<inf>3...
Electrons extracted from a glowing filament may be used to ionize gases. This is the basis for the electron bombardment ion source (seeFigure 1). A satisfactory electrode arrangement enables the production of a beam of ions much more nearlyhomogeneousin energy than with the arc, greatly simplifyi...
