Eduard Vladimirovich Shpolsky, also Shpolsk'ii, Shpolskii (russian: Эдуард Владимирович Шпольский, born September 23, 1892 in Voronezh – died August 21, 1975 in Moscow) was a Russian and Soviet physicist and

He reasoned that carcinogens should possess physical properties distinct from harmless substances, and although no such link was ever found, his studies led to the discovery of Shpolsky effect. In 1952 Shpolsky, Ilyina and Klimov published an article in ''Doklady Akademii Nauk'' asserting that complex organic substances that normally do not have clearly defined spectral lines do, in fact, emit or absorb them at low temperatures when mixed with specific organic solvents. Use of the solvent, forming a snow-like

The method, although lacking solid theoretical foundation, provided extreme spectral selectivity and became a major improvement in detecting 3,4-benzapyrene in the 1960s.Bolotnikova 1992, p. 188 In 1961 Karl Rebane suggested that Shpolsky effect was an optical
