Asymmetry mercury

Figure 19. It is assumed here that the concept of the ellipsoids of observation apply to all fields moving with the velocity of light, such as electric or gravitational fields. Thus, precession of the perihelion of Mercury (the rotation of its elliptic orbit) can be explained by the asymmetry of the gravitational forces as the planet advances toward (resp. retreats from) the sun.

Regarding the chemical behavior of (-)-emetine (1), the stereochemistry of asymmetric electroreductions of bromocyclopropanes at a mercury cathode in the presence of adsorbed 1 has been studied 95,96). Bertz et al. (97) have reported asymmetrie induction (with 70 30 R/S ratio, but in only 6% chemical yield) that occurred in the conjugate addition of an (-)-emetine-incorporating phenylamidocuprate to 2-cyclohexenone. Fraser-Reid s group 98,99) has reported that the NH group of 1 is readily protected as the A-pent-4-enoyl derivative, which can be rapidly... 

The lattice distortion of a-mercury indicates that even in the crystal, there is actually a small amount of asymmetry in the pair interactions. 

An experimental set-up similar to the one used in polarization spectroscopy is employed in experiments testing atomic manifestations of parity violation in the electro-wealc interaction. [9.359-9.361]. The experiments are important for testing the Standard Model hi elementary particle physics. Right-left asymmetries in atomic physics are of the order of 1 10 . A small optical rotation detectable using crossed polarizers is induced by interference between neutral weak and electromagnetic interactions in atoms. The most accurate experiments deal with heavy elements such as mercury, thalhum, lead and bismuth [9.362, 9.363]. Another way of probing the parity violation is to observe the strength of certain forbidden transitions, notably the 7 —...
