Nikolai Aleksandrovich Borisevich (b. 21.09.1923, v. Luchnoy Most, Berezin district, Minsk region – 25.10.2015), physicist, state and public figure. Academician of the National Academy of Sciences of Belarus (1969; corresponding member since 1966), academician of the Academy of Sciences of the USSR (1981), Russian Academy of Sciences (1991), foreign member of the Czechoslovak Academy of Sciences (1977), foreign member of the Slovenian Academy of Sciences and Arts (1981), full Member of the European Academy of Sciences, Arts and Literature (1991), Honorary Doctor of Science at the Jena University named after F. Schiller (1983), Doctor of Physico-Mathematical Sciences (1965), Professor (1967). Hero of Socialist Labor (1978). Honored Scientist of the Republic of Belarus (1994). Participant of the Great Patriotic War and partisan movement in Belarus.
Studies on luminescence and spectroscopy of complex molecules, quantum electronics, infrared technology. He developed a statistical theory of photophysical processes in complex molecules, introduced new spectroscopic characteristics of molecules, and developed methods for their determination; Relations have been obtained linking all the main spectral and luminescent characteristics of complex molecules. The problem of anti-Stokes luminescence is solved. A new phenomenon of stabilization-labilization of electronically excited polyatomic molecules has been discovered, registered as a scientific discovery. Thermally activated and laser-induced delayed fluorescence, luminescence upon electrical excitation, polarization of luminescence and stimulated radiation, as well as generation of complex molecular vapor have been discovered and studied. With the help of pico- and femtosecond laser pulses, ultrafast relaxation processes and structural rearrangements in organic molecules were investigated; when cooling molecules in supersonic jets, fine-structured spectra of free molecules and complexes were obtained, which made it possible to draw important conclusions about their structure.
Author of more than 300 scientific papers, incl. 3 monographs.
Lenin Prize in 1980 for the creation of a new scientific direction - spectroscopy of free complex molecules. State Prize of the USSR in 1973 for research on the scattering of radiation by dispersed systems and the creation of a new class of optical filters for a wide region of the infrared spectrum, State Prize of the Republic of Belarus in 1998 for the series of works "Dynamics of rotational motion of electronically excited polyatomic molecules in a gaseous medium". Prize of the National Academy of Sciences of Belarus and the Siberian Branch of the Russian Academy of Sciences named after academician V.A. Koptyug (2001).
