Sublimated Photoconductive Films of CdS Type: History and Modernity

Brief history is given of the physical properties study at Saratov University and in the USSR of sublimated photoconducting films of CdS type that plays a prominent role in photoelectric researches, for which the cadmium sulfide served as a model substance. An addition of lead sulfide to cadmium sulfide has increased the speed of photoresponse and the resistance to degradation.

Scientific and Educational Physical Schools in Saratov (on the 80th Anniversary of the Saratov Region)

We present a brief history of scientific-educational schools in physics in Saratov since the founding of Saratov University (1909). Saratov belongs to Russian industrial centers that have extensive experience of research, development of technology of electronic equipment, training for this field of science and technology. The outstanding scientist Peter N. Lebedev was at the forefront of physical education and science in Saratov.

Afterword to the Anniversary of the Faculty of Physics of SSU

We present information on the meeting of graduates from physical faculty of Saratov National Research State University, dedicated to the 70th anniversary of the faculty. Physical education in the university was formed under the influence of the greatest Russian physicists Peter N. Lebedev and Nikolai N. Semenov, the winner of the 1956 Nobel Prize. Graduates from the faculty of various specialties (on vacuum and solid state electronics, radiophysics, optics, chemical physics, laser physics and biophotonics) celebrated the anniversary of the faculty on February 19, 2016.

D. I. Blokhintsev about the Spiritual Foundations of Scientific Creativity

The Corresponding Member of the USSR AS Dmitrii Ivanovich Blokhintsev (10.01.1908 — 29.01.1979), one of the pioneers of atomic science and technology in USSR, the organizer and the first director of the Joint Institute for Nuclear Research in Dubna, has his original opinions about the spiritual foundations of scientific creativity. In this brief paper, we try to treat his opinions and show how they are working in the modern physics and cosmology of the Early Universe.

Molecular Modeling and Vibrational Spectra of 4,4,’-clorobenzophenone

Vibrational infrared and Raman spectra of 4,4’-chlorobenzophenone have been measured at room temperature in the ranges 400–3200 and 0–3200 cm−1 respectively. Modeling of structure and vibrational spectra has been performed by a density functional theory method B3LYP/6-31+g(d) and 6-31-g(d). Energy, structure, components of the dipole moment and polarizability tensor, force constants, frequencies of normal modes in harmonic approximation and their intensities in the IR and Raman activity have been calculated. Interpretation of measured spectra is given.

AD HOC Quantization of the Electromagnetic Momentum for a Dispersive Medium

Background and Objectives: There are two types of linear field momentum in the macroscopic electrodynamics: Minkowski momentum, and Abraham momentum. The first is conserved inside the uniform substance, the second is included into the momentum balance in relation to the center of energy. These two quantities must comply with two measures of photon momentum. Unfortunately, the ad hoc quantization of the Minkowski momentum in dispersive medium leads to the theoretical photon momentum, which differs from the observed momentum.

IR Spectra of Triphenyl Phosphite and Their Interpretation by Molecular Modeling

Background and Objectives: IR spectra of triphenyl phosphite (TPhPh) were measured in liquid (at 320 K), glassy and glacial phases and in hexagonal (metastable) and monoclinic (stable) crystal phases at 12 K. The observed differences in the spectra is a consequence of the implementation of the conformers of different types in the sample. To substantiate this hypothesis, structurally dynamic models of the three most probable conformers (I –III) were built. The conformers are different in angles of rotation of the phenyl rings around the C-O bonds.

Modeling of Vibrational Spectra of L-tryptophan in Condensed States

Background and Objectives: This work is devoted to the interpretation of IR and Raman spectra of Trp in the condensed states. For this purpose, we calculated the complexes in the zwitterionic form of Trp with the water molecules. Obtained results allow us to determine the influence of hydrogen bonds on the vibrational spectra of Trp in the aqueous solution and solid state.

Electromagnetic Momenta at Wave Refraction into Dispersive Medium

Background and Objectives: There are two types of a field momentum in the classical electrodynamics, namely, the Abraham momentum, and the Minkowski momentum. The question arises how these momenta are conserved in the refraction on the boundary surface of a medium.

Methods: The electromagnetic stress tensor and momentum density in a dispersive medium, including the case of negative permittivity and negative permeability, are derived and used in this paper.
