X-ray emission and absorption spectra of carbon nitride films prepared by laser ablation were measured. The carbon x-ray spectra of films obtained in a nitrogen atmosphere were different from those of a film prepared in vacuum. It was found from DV-Xa molecular orbital calculations on x-ray spectra

The DV-Xa molecular orbital (MO) calculation method was applied to the B K-V x-ray emission spectra of hexagonal (h-), cubic (c-) and wurtzite (w -) type boron nitrides (BN). The calculated B 2p density of states (DOS) was in good agreement with the B K-V x-ray emission. The main peaks and low-energ
The cation 2 undergoes a number of other interesting reactions (Scheme 2). Thus, treatment with a slight excess of sBu,AIH (CH,C1,, -78Β°C) affords a 2:3 mixture of the starting material and the q4-buta-l ,3-diene complex 5, which could be separated by column chromatography (A1,0, grade 11, benzene/h
