We study nonlinear absorption behaviors of 5, 10, 15, 20-tetrakis(4-hydroxyphenyl)porphyrins with the central metal ions: Zn(2+), Ni(2+), Co(2+), and Fe(3+) by open aperture Z-scan technique with 65 ps or 4 ns pulse duration. For 65 ps pulse duration the filled d shell compounds exhibit nonlinear absorption while the unfilled d shell compounds exhibit saturable absorption. For 4 ns pulse duration Ni, Co and Fe compounds exhibit nonlinear absorption at high fluence while Ni compound exhibits saturable absorption at low fluence. The observed nonlinear absorption behaviors depending on the central metal ion and pulse duration are discussed using excited-state lifetimes found from pump-probe spectroscopy. (C) 2011 Elsevier B.

Vibrational spectroscopy of hydrogen-bonded systems: Six-dimensional simulation of the IR spectrum of F-(H2O) complex Toffolı, Danıele; Sparta, Manuel; Christiansen, Ove (Elsevier BV, 2011-06-24) The vibrational dynamics of the F-(H2O) complex is studied using highly accurate six-dimensional molecular potential energy and dipole moment surfaces calculated at the CCSD (T)/cc-pVQZ and CCSD (T)/augcc-pVTZ levels with a multiresolution approach. The extent of mode-coupling is investigated with full vibrational configuration-interaction (FVCI) calculations. Coriolis coupling effects are also included with the aim to obtain quantitative agreement with the experimental data available. The vibrational absor...
STRUCTURAL STABILITY AND ENERGETICS OF AS, SB AND BI MICROCLUSTERS - EMPIRICAL MANY-BODY POTENTIAL-ENERGY FUNCTION CALCULATION Katırcıoğlu, Şenay (Elsevier BV, 1991-08-09) The structural stability and energetics of As, Sb and Bi microclusters having 3-7 atoms have been investigated by using a recently developed empirical many-body potential energy function (PEF), which comprises two- and three-body atomic interactions. The PEF satisfies both bulk cohesive energy per atom and bulk structural stability exactly. It has been found that the most stable structures of As3, Sb3 and Sb4 microclusters are in linear form with D-infinity-h symmetry, Bi7 is in hexagonal pyramid form with ...
Bosonic helium droplets with cationic impurities: Onset of electrostriction and snowball effects from quantum calculations Coccia, E.; Bodo, E.; Marinetti, F.; Gianturco, F. A.; Yıldırım, Erol; Yurtsever, M.; Yurtsever, E. (AIP Publishing, 2007-03-28) Variational Monte Carlo and diffusion Monte Carlo calculations have been carried out for cations such as Li(+), Na(+), and K(+) as dopants of small helium clusters over a range of cluster sizes up to about 12 solvent atoms. The interaction has been modeled through a sum-of-potential picture that disregards higher order effects beyond atom-atom and atom-ion contributions. The latter were obtained from highly correlated ab initio calculations over a broad range of interatomic distances. This study focuses on ...
Optical properties of Meloxicam in the far-infrared spectral region Aytekin, Yusuf Samet; Zaczek, Adam; Korter, Timothy M.; Heilweil, Edwin J.; Esentürk, Okan (Elsevier BV, 2018-08-17) One of the most commonly used nonsteroidal anti-inflammatory active pharmaceutical ingredient called Meloxicam has been characterized spectroscopically both by Terahertz (THz) time domain spectroscopy (THz-TDS) and by Fourier Transform Infrared (FTIR) spectroscopy in far-IR regions of electromagnetic spectrum; 0.2 THz-20 THz. While many relatively sharp features are observed in the far-IR range between 2 THz-20 THz as expected for being an organic substance, very distinct and relatively strong absorption ba...
Associative behaviour and effect of functional groups on the fluorescence of graphene oxide Ozcan, Sefika; Vempati, Sesha; Çırpan, Ali; Uyar, Tamer (Royal Society of Chemistry (RSC), 2018-01-01) We have juxtaposed the structural, vibrational and emission properties of graphene oxide (GO) with various degrees of reduction with and without a model dispersant, unveiling a strong associative behavior between GO sheets and the influence of H-bonds. The interlayer spacings are similar to 0.84 and 0.78 nm for the as prepared and reduced samples. -OH groups are predominantly effected by the photo-thermal reduction. Also we note some regeneration of > C=O and -COOH groups in reduced samples. Clear changes t...
