Fine and hyperfine structure, and isotope shifts in the arc spectrum of mercury. I

Precise determination of wavenumbers is reported corresponding to transitions observed in the infrared region of the arc spectrum of 202Hg, with an accuracy of about 0.005 cm-1. Isotope shifts of the seven stable isotopes and hyperfine structures (for both odd 199 and 201 isotopes) for excited levels in 6snl (with n<=10, l=0, 1, 2, 3) and d9s2p(6p') configurations are given with a relative precision of about 0.5%.
