✦ Synopsis

In this paper, the absorption spectrum of PbWO 4 :Cr 3+ crystals is measured at room temperature in the wavelength range from 340 to 520 nm. The d-d transitions of Cr 3+ ions in PbWO 4 crystals with tetragonal symmetry are calculated by the crystal-field theory. The theoretical results are in good agreement with the experiments. The experimental bands have been assigned as the tetragonal symmetry field components of transitions.

In the electron impact mass spectra of N

In the electron impact mass spectra of N,N′-diaryl-1,3-phenylenediamines, recorded under conditions generating the molecular ion as a base peak, the most important step involve a β-aromatic cleavage with H rearrangement, leading to the expulsion of a neutral arylamine; this fact can be used in meta isomer identification since for the corresponding 1,2- and 1,4-isomers the expulsion of an aryl radical is a competitive process
