The magnitude of the cross-sections is not the only enigma in the mercury experiments. The second curiosity concerns the reason why the four molecules N2, CO, H20 and D20 should efficiently induce spin-orbit relaxation, whereas most other simple molecules (e.g. C02, NH3) are rather inefficient119,179. 

The excitation transfer has been investigated by studying the sensitized fluorescence of sodium, arising from the decay of several S, P, and D states that have energies close to the excitation energy of the 6 P2 (and 6 P0) state in mercury. Experiments of this type have been reported by the groups of... 

Boerhaave s first experiment on 27 October 1693 is the production of a tincture through mixing and digesting sulphur and oil, soon followed in 1694 by similar experiments involving sal ammoniac, antimony and mercury. On the third of December 1695 Boerhaave wrote the first entry in which he describes how he tried to create gold out of purified mercury and sulphur. In the years between 1693 and 1718 Boerhaave must have changed his mind about the possibility of transmutation as the experiments in the second notebook mainly describe the process of purifying metals, mercury in particular. The results of Boerhaave s mercury experiments have been published in the Philosophical Transactions. Moreover, Boerhaave wrote about them to his friends Bassand and Mortimer, who was also secretary of the Royal Society. 

Impregnation Process. In both processes the first step in the impregnation of wood is carried out by evacuating the air from the wood vessels and cell lumens (27). Any type of mechanical vacuum pump is adequate if it can reduce the pressure in the apparatus to 750 mm of mercury or less. Some industrial producers only reduce the pressure to about 711 mm of mercury. Experience has shown that the air in the cellular structure of most woods is removed as fast as the pressure in the evacuation vessel is reduced. Pumping for 30 min at 1 mm pressure is sufficient to remove the air. The vacuum pump is isolated from the system at this point. 

The statue of Lavoisier later erected behind the Madeleine disappeared in World War II. It has been said to be of Condorcet (also the bust in the Louvre), but the marble bust at Versailles (1801) is of Lavoisier. The statue showed the famous mercury experiment and was obviously intended to be Lavoisier s. ...
