Optical activity of the incommensurate phase of Rb2ZnCl4

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

comparison of catalytic activity of heteropoly compounds in the synthesis of bis(indolyl)alkanes.

heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

Simulation of normal Rb2ZnCl4 near the incommensurate transition.

First principles theoretical explanation of incommensurate behavior in Rb2ZnCl4.

E.P.R. investigations of commensurate-incommensurate structural phase transitions through " forbidden hyperfine lines ". Application to Rb2ZnCl4 : Mn2+

2014 A detailed investigation of the hyperfine structure of the 1/2 ~ 1/2 electronic transition, for a paramagnetic probe with S ~ 3/2, seems to be well adapted to the study of incommensurate phases. We exemplify the method in the case of Rb2ZnCl4 : Mn2+. J. Physique LETTRES 41 (1980) L-499 L-502
