The Jahn–Teller effect (JT effect or JTE) is an important mechanism of spontaneous symmetry breaking in molecular and solid-state systems which has far-reaching consequences in different fields, and is responsible for a variety of phenomena in spectroscopy, stereochemistry, crystal chemistry, molecular and solid-state physics, and materials science.
Second-order Jahn-Teller distortion provides a rigorous and first-principles approach to the distortion problem. The interactions between the HOMOs and LUMOs to afford a new set of molecular orbitals is an example of second-order Jahn-Teller distortion.
In their early 1957 paper on what is now called pseudo Jahn–Teller effect (PJTE), Öpik and Pryce [2] showed that a small splitting of the degenerate electronic term does not necessarily remove the instability and distortion of a polyatomic system induced by the Jahn–Teller effect (JTE), provided that the splitting is sufficiently small (the two split states remain "pseudo degenerate ...
Looks like Machine Gun Kelly is going by a new name. MGK (aka Colson Baker) has seemingly asked fans and photographers to call him just "Machine," a change that comes after he spotted a sign at a ...
George Kelly Barnes (July 18, 1895 [1] [2] – July 18, 1954), [3] better known by his nickname "Machine Gun Kelly", was an American gangster from Memphis, Tennessee, active during the Prohibition era.
In a candid new interview, Machine Gun Kelly opened up about when his late father stood trial for murder at 9 years old. Kelly, 34, explained during the Monday, August 5 episode of Bunnie XO’s ...
Last week, mgk dropped his newest song, "Don't Let Me Go." In the lyrics and the subsequent music video, mgk doesn't hold back about his struggles, even alluding to suicidal thoughts.. He also ...
In this structure, the copper centers are octahedral. Most copper(II) compounds exhibit distortions from idealized octahedral geometry due to the Jahn-Teller effect , which in this case describes the localization of one d-electron into a molecular orbital that is strongly antibonding with respect to a pair of chloride ligands.
