TL;DR: In this paper, the basic properties of molybdenum and the methods of producing metallic molybordenum are described, and the focus is directed to various applications of the molybenzenum alloys and compounds such as catalysts, lubricants and refractory ceramics.
Abstract: The basic properties of molybdenum and subsequently the methods of producing metallic molybdenum are described. Selected classes of important inorganic compounds (molybdenum halides, molybdenum oxides, iso- and hetero-polyoxomolybdates) as well as molybdenum hexacarbonyl and hybrid inorganic–organic materials are presented. Thereafter the focus is directed to various applications of metallic molybdenum, its alloys and compounds such as catalysts, lubricants and refractory ceramics. In conclusion, molybdenum’s medicinal role and the antimicrobial activity of MoO3 and solid solutions Mo

TL;DR: In this article, the infrared and Raman spectra for 92MoF6 and 100MoFs6 vapor were reported for partial resolved PQR structure with an asymmetric Q branch, from which the band origin ν0 can be estimated.
Abstract: Infrared and Raman spectra are reported for 92MoF6 and 100MoF6 vapor (isotopic purities ≳ 97%). The infrared‐active stretching fundamental ν3 exhibits partially resolved PQR structure with an asymmetric Q branch, from which the band origin ν0 can be estimated; the isotopic frequency shift for the band origin is Δν3 = 8.1±0.3 cm−1. The shift of the Q branch maximum of the other F1u fundamental is Δν4 = 3.0±0.4 cm−1. With the aid of these two isotope shifts, the general quadratic symmetry and valence force constants of MoF6 are calculated. The primary valence force constants are fr = 4.94 and fα ? 0.22 mdyn/A. The force fields of MoF6, WF6, and UF6 are compared and discussed.
