Boron Monoxide and Dioxide. High temperature vapor phases of BO, B203, and B02 have been the subject of a number of spectroscopic and mass spectrometric studies aimed at developing theories of bonding, electronic structures, and thermochemical data (1,34). Values for the principal thermodynamic functions have been calculated and compiled for these gases (35).

Porous anodic alumina is a very promising material for nanoelectronics. The injection of different types of impurities inside an alumina matrix can substantially improve its electrophysical properties. It is very important to study the local environment (chemical bonds, electronic structure, etc.) of injected atoms for understanding physical principles of the electronic elements formation. A number of techniques can be used to determine a chemical state of atoms in near surface layers. The most informative and precise technique is X-ray photoelectron spectroscopy. At the same time, Auger electron spectroscopy (AES) is also used for a chemical analysis [1] and can be even applicable for an analysis of dielectrics. The chemical state analysis of Ti and Cu atoms implanted into anodic aliunina films was carried out in this work by means of AES. 

The first stable actinide complex of carbon monoxide was prepared by reaction of (Me3SiC5H4)3U (Cp 3U) with CO in solution or in the solid state to produce Cp 3U(CO), which reversibly dissociates CO. Cp 3U(CO) exhibits a carbonyl stretch in the IR spectrum at 1976 cm or approximately 170 cm lower than the uco for free carbon monoxide. This is taken as an indication of uranium-to-carbonyl r-back bonding see Back Bonding. Electronic structure calculations on the model complex CpsUCO indicated a significant U 5f-CO 2n...

First we accentuate that the most important retrosynthetic mle is related to the basic property of the C-C bond, electronic structure and electronic charges of the fragments that emerge on disconnection of this bond. The mle states that disconnection should follow the correct mechanism. Products of disconnection are synthons—anionic or cationic fragments or radicals. Behind synthons, however, real molecules should exist, denoted as reagents or synthetic equivalents. 

The results of the N-Ol bond electronic structure, studied in the real space using topological analysis of ELF, will vary depending on the computational method used. At the DFT(B2PLYP)/aug-cc-pVTZ computational level, the N-Ol bonds in both conformers are described by two monosynaptic attractors, V(01) and V(N). Such ELF-topology is characteristic for the protocovalent bond. The core and valence attractors in the syn and anti conformer of the nitrous acid are shown in Fig. 19.3. Similar analysis, carried out using the B3LYP hybrid electron density...
