In this introductory exploration of the title theme, we treat a positron as a light nucleus and work within the quasimolecule approximation to obtain, for the first time, adiabatic potential energy curves for its scattering by the He atom. We then show that different elastic and inelastic processes that contribute to the total scattering cross section can be rationalized in molecular terms as d...
Electronic Structure Theory describes the motions of electrons in atoms or molecules. Generally this is done in the context of the Born-Oppenheimer Approximation, which says that electrons are so much lighter (and therefore faster) than nuclei that they will find their optimal distribution for any given nuclear configuration. The electronic energy at each nuclear configuration is the potential ...

A molecular film of pulmonary surfactant covers the hydrated lung epithelium to the air. We recently showed that the film exhibits a locally strongly variable electrical surface potential of up to several hundred millivolts. The potential arises from aligned molecular dipoles of the molecules. In the case of the complex structural organization of the phase-separated film of pulmonary surfactant...
The laser excited, jet-cooled Ã2A′′ 2 − X̃2E′′ 1 electronic spectrum of the cyclopentadienyl radical yields detailed information about the vibronic structure of both its à and X̃ states. A straight-forward assignment of the à vibronic structure is presented. The X̃ state vibronic structure reveals a comprehensive picture of the Jahn-Teller distortion of its potential energy surface. The molecular ...
Ro-vibrational calculations on a recent ab initio potential energy surface for H: (W. Meyer et al., J. Chem. Phys. 84, 891 (1986)) are presented for the isotopomers H,_.D: (n = 0, 1, 2, 3). These calculations employ refinements recently developed for nuclear motion calculations and are thus of very high accuracy. The rotational levels with .I G 4 are fitted to standard vibrationrotation Hamilto...
The aims of this project are to investigate the effects of Isoniazid drug adsorption on the geometrical and electrical structure of pristine and Ni-doped Gallium nitride nanotube (GaNNTs). For this purpose, 24 different configuration models are considered for adsorbing Isoniazid on the surface of nanotube and then all considered structures are optimized by using density function theory (DFT) ...
The most commonly used method for the production of thin films is based on deposition of atoms or molecules onto a solid surface. One of the suitable method is to produce high quality metallic, semiconductor and organic thin film is Ionized cluster beam deposition (ICBD), which are used in electronic, robotic, optical, optoelectronic devices. Many important factors such as cluster size, cluster...
