Abstract:

Radiation of mercury emission line at 253.7 nm and its absorption is widely used in many spectroscopic, photochemical, analytical, and magnetometric tasks as well as in other scientific and engineering applications. Physical and chemical peculiarities of mercury as well as the demand to determine its microconcentrations (as small as the background level) made the mercury gas analyzers to be a separate class of analytical devices. In this paper we present the line parameters which one should take into account in applied investigations (line width, collision broadening and shift, Zeeman splitting, isotopic and hyperfine structure). The data from references are supplemented with the results obtained by the authors.
