PE spectra can show bands corresponding to ion states that cannot be accessed from the ground-state molecular configuration by the removal of one electron. Such signals can normally be represented by removal of one electron synchronized with excitation of another they are hence referred to as many-electron processes, and the additional satellite structure accompanying the primary band as shake-up structure. A classic example of a two-electron transition is the very weak band found in the spectrum of atomic mercury for the process shown in equation (12) ...

The conclusions presented above can be applied in designing experiments on chemical identification and studies of element 112. There is little doubt that the element is a congener of mercury, at least equally volatile and chemically inert. Then proper chemical environment can be even simpler than in the case of HSO4. However, the experimental technique must allow for the possibility that element 112 is much more volatile and chemically inert than mercury. The problem is to guarantee the registration of the element (not to lose it) even if it resembles Rn, rather than Hg, in volatility and inertness. Atomic mercury in tracer quantities can be transported by inert gas at ambient temperature through tubes made of various materials. However, it adsorbs onto some metals, in particular, on gold. 

Spectra of atomic mercury dissolved in cyclohexane, 1,2-dichloroethane, and absolute methanol have been examined as part of a search for simple condensed systems. The spectrum of the solvent was carefully subtracted from that of the mercury after the 10-cm paired cells were precisely balanced with solvent in both cells. Spectra of Tg-resolved distributions, Fig. 2, reveals that the spectra are much more complicated than a priori expectation.

The equipment used was a Barringer airborne mercury spectrometer (BAMS, Figure 1), an atomic absorption spectrophotometer specifically designed and built to isolate the 2536.5-A emission and absorption spectrum characteristic of atomic mercury vapor. The equipment was originally developed for mineral exploration purposes and for analysis of laboratory soil samples subsequent design improvements led to the rapid response time (1 sec) and high resolution (nanogram per cubic meter) required for airborne use (1). 

In a mass spectrometric study, Amot and Milligan observed that Hg2 ions were formed in a collisional process following excitation of mercury vapor by the impact of electrons with insufficient energy to ionize atomic mercury. More detailed studies, in which the appearance potential of Hg2 was determined, led the authors to conclude that Hg2 was formed by an associative ionization reaction completely analogous to (11). Similar conclusions could be made from the data of SnaveV if this latter author s energy scale was adjusted to take into account the formation of Hg2 by associative ionization.

The mercury-water interaction potential is derived in a similar manner from Hartree-Fock calculations of the interaction of a water molecule with 9-atom mercury clusters [36]. Potential functions fltted to the ab initio data were used to calculate the interactions of water molecules with a lattice of mercury atoms [7]. During the simulation this lattice was either kept rigid (Figure 6 and Figure 7) or the liquid water/liquid mercury interface was simulated (Figure 3). 

Whilst the interaction of excited atomic mercury with hydrogen or hydrogen-containing molecules yields atomic hydrogen, the reaction Hg + N2O -> Hg + N2 + O gives atomic oxygen. This reaction is used for the production of 0( P) atoms (see e.g. [10, 410]).

Bache and Lisk determined dmethylmercury and methylmercury-chloride in fish by emission spectrometry in a helium plasma. Dimethylmercury was chromatographed on a 2ft glass column of Chromosorb 101. Methyl mercury salts were separated on a 6ft column of 1 1 0V-17/QF-1. The separated compounds were detected by their emission spectra at the 2537A° atomic mercury line which gave a linear response for O.l-lOOyg of injected methylmercurychloride ... 

Owing to their s electron configuration mercury atoms are less reactive and are stable in many solvents such as alkanes and water under ambient conditions [27,146,147]. However, the solubility of atomic mercury is rather low (= 10" M).
