The Institute of Spectroscopy Russian Academy of Sciences (ISAN) (in some sources the abbreviation used is ISAS, IS RAS) is a Russian research institution located in Troitsk, Moscow At present (2010) ISAN has eight research departments, which activity covers practically all kinds of spectroscopies: atomic, molecular, plasma, gases, liquids, condensed matter, amorphous solids, glasses, crystals, nanostructures, polymers, biological systems. The available equipment allows for measurements in a broad spectral range; with ultimate spectral, spatial and temporal resolutions; in a broad range of temperatures and measurement times; with application of external fields. ISAN educational activity includes a program for Diploma Students, Ph.D. and Doctorals for science, R&D and industry. The "Chair of Nanooptics and Spectroscopy" of Moscow Institute of Physics and Technology and the "Chair of Quantum Optics and Photonics" at the National Research University Higher School of Economics (HSE) are based at ISAN. Institute of Spectroscopy is co-founder of EU Virtual Institute of Nano-Films History Institute of Spectroscopy of Russian Academy of Sciences (ISAN) ( before 1991 - Institute of Spectroscopy of Soviet Union Academy of Sciences) was founded in 1968 on the basis of laboratory of Spectroscopy Committee of Soviet Union Academy of Sciences. Initial goals of the laboratory included the support of scientific and organizational activities of the Spectroscopy Committee, work on a number of technical problems, training of staff, etc. As time passed, activities of the lab reached far beyond its initial scope. The laboratory has become the place of full-scale research focused on spectral instrument making and implementation of atomic and molecular spectroscopy in national economy. Significant scientific and practical results were obtained. Laboratory of the Spectroscopy Committee turned into an independent scientific institution with highly skilled specialists. On 10 November 1967 Presidium of Academy of Sciences of USSR approved a resolution to reorganize the laboratory of Spectroscopy Committee into an Institute for Spectroscopy AS USSR to form a USSR head body in the field of spectroscopy. Soon after that, the Government Committee for Science and Technology gave consent to create an institute and on 29 November 1968, Presidium AS USSR decided to reorganize the Laboratory into an institute. As was proposed by secretary academician L.A. Artsimovich, construction of the Institute building was planned to take place in the Krasnaya Pakhra Scientific Centre, which was being developed at the time and already included the Pushkov Institute of Terrestrial Magnetism, Ionosphere and Radio Wave Propagation and Institute
