متن کاملHigh-harmonic transient grating spectroscopy of NO2 electronic relaxation.
We study theoretically and experimentally the electronic relaxation of NO(2) molecules excited by absorption of one ∼400 nm pump photon. Semiclassical simulations based on trajectory surface hopping calculations are performed. They predict fast oscillations of the electronic character around the intersection of the ground and first excited diabatic states. An experiment based on high-order harm...
متن کاملinvestigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
15 صفحه اولUnusual relaxation pathway from the two-photon excited first singlet state of carotenoids.
Transient infrared and visible absorption measurements along with density functional theory (DFT) calculations on carotenoids 8'-apo-beta-caroten-8'-al (I) and 7',7'-dicyano-7'-apo-beta-carotene (II) were used to explore the nature of a long-lived species observed in transient infrared absorption measurements following two-photon excitation (Pang et al. J. Phys. Chem. B 2009, 113, 13806). The l...
متن کاملDynamics of excited-state conformational relaxation and electronic delocalization in conjugated porphyrin oligomers.
We have investigated the influence of nuclear geometric relaxation on the extent of the excited-state electronic delocalization in conjugated zinc porphyrin oligomers using ultrafast transient photoluminescence spectroscopy. By use of metal-coordinating templates that force the oligomers into specific geometries in solution we are able to distinguish clearly between relaxation effects arising f...
