Conformational Information from Vibrational Spectra of Styrene, trans-Stilbene, and cis-Stilbene
Two electron correlation theories, second-order Møller-Plesset perturbation (MP2), and density functional (DFT) methods have been adopted to obtain fully optimized structures of styrene, trans-stilbene, and cisstilbene. Full geometry optimizations with MP2 shows that the nonplanar conformations of styrene and trans-stilbene are preferred by 0.24 (styrene) and 0.80 kcal/mol (trans-stilbene), res...
متن کاملAn Experimental and Theoretical Investigation of the Olefinic Carbon Chemical Shift Tensors in trans-Stilbene and Pt(η-trans-stilbene)(PPh3)2
The olefinic carbon chemical shift tensors of trans-stilbene-R,â-C2 (1) and (trans-stilbene-R,â-C2)[bis(triphenylphosphine)]platinum(0) (2) have been characterized by solid-state 13C NMR spectroscopy. Analyses of the 13C NMR spectra obtained for stationary powder samples of 1 and 2 at 4.7 and 9.4 T yield the principal components of the carbon chemical shift tensors. The presence of a homonuclea...
متن کاملOptical stochastic cooling.
In this paper, we consider the utilization of optical amplifiers with bandwidth ∆f ∼= 1014Hz for use in stochastic cooling. It is shown that quadrupole and dipole wigglers can be used as pickups and kickers respectively. The proposed method increases the application of the stochastic cooling method beyond the traditional area of proton-antiproton cooling. For example, the method can also be app...
متن کاملMagneto-optical cooling of atoms.
We propose an alternative method to laser cooling. Our approach utilizes the extreme brightness of a supersonic atomic beam, and the adiabatic atomic coilgun to slow atoms in the beam or to bring them to rest. We show how internal-state optical pumping and stimulated optical transitions, combined with magnetic forces, can be used to cool the translational motion of atoms. This approach does not...
متن کاملcontrol 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...
