System of Recording Radiation for Analysis of Third-Order Correlation Functions

A system of recording the triple correlation of a photodetection signal for the spectral analysis of optical radiation is proposed. The results of the recording of the correlation components and of the computer calculation of the laser radiation spectral line profile are presented.     

IR spectroscopic and electron microscopic investigations of colored lead silicate glasses

The information on obtaining colored transparent glasses of lead silicate composition is given in the article. Cr₂O₃, Mn₂O₃, Fe₂O₃, Ni₂O₃, Y₂O₃, Ce₂O₃, Nd₂O₃, and Er₂O₃ are used as colorants. Structural features of obtained glasses are investigated by methods of infrared spectroscopy and electron microscopy.     

Iron aspartate complexes and model processes of their formation

Complexation of iron(II) and iron(III) ions with aspartate anions was studied by measuring oxidative potentials. The empirical formulas, stability constants, pH ranges, and mole fractions of the resulting iron aspartate complexes were determined using an oxidative function and a new concept of modeling complexation equilibria.
