The vapor phase fluorescence spectra of p-benzoquinone-84 and & are reported and discussed in relation to the assignment of the low lying singlet states. The low temperature, polarized single crystal electronic absorption spectra of p-benzoquinone and several of its isotopic derivatives are reported. From the isotope shifts and band polarizations of the various vibronic origins, a detailed vibr...
The 1(3)Σu (-)←X(3)Σg (-) transition of linear HC5H (A) has been observed in a neon matrix and gas phase. The assignment is based on mass-selective experiments, extrapolation of previous results of the longer HC2n+1H homologues, and density functional and multi-state CASPT2 theoretical methods. Another band system starting at 303 nm in neon is assigned as the 1(1)A1←X˜(1)A1 transition of the cu...
در این تحقیق اتصال پپتیدی نانولوله به صفحات گرافن مورد بررسی قرار گرفته است. از میان جنبه های مختلف قابل بررسی برای این ساختارها، مطالعات ساختاری، مطالعات مربوط به انرژی تشکیل پیوند، مطالعاتnmr) )neuclear magnetic resonance و nuclear quadrupole resonance (nqr)و molecular electrostatic potential (mep)، مطالعات مربوط به شکاف انرژی (band gap)هریک از این هیبریدهای نانولوله - گرافن و همچنین بررسی ان...
انتقال قرارداد نقش سازنده و فزاینده ای در عرصه فعالیت های اقتصادی و چرخه مبادلات و معاملات تجاری دارد. انتقال قرارداد بنا بر مقتضیات اقتصادی مستلزم آثار، شرایط، مفروضات و ملزوماتی است که از بسیاری جهات، اصول و مبانی حقوق تعهدات را به چالش می کشد. مطابق حقوق تعهدات، ماهیت توافقی و تراضی و اصل نسبی بودن و قابلیت استناد قرارداد، ملاک ارزیابی انتقال قرارداد می باشند. از دیدگاه اقتصادی، انتقال سرمای...
One of the basic combinatorial optimization problems is the assignment problem that deals with assigning jobs to individuals. In traditional assignment problems, n jobs usually assign to n individuals such that the total cost is minimized or the total profit is maximized. However, in numerous real-life applications, various attributes could be considered in assignment problems while data (obj...
Infrared combination bands of the polar isomer N2O dimer are observed for first time, using a tunable infrared laser source to probe pulsed slit-jet supersonic expansion in nu1 region (~2240 cm-1). One band involves torsional (out-of-plane) intermolecular mode and yields frequency 19.83 cm-1 if associated with out-of-phase fundamental (N2O nu1) vibration monomers dimer. The other band, which is...
We consider a model of Cournot competition with congestion motivated by recent initiatives in wireless spectrum policy to allow commercial use of spectrum assigned to government agencies. A key feature of such spectrum is that it may be intermittently available due to the incumbent government user’s activity. In our model, wireless Service Providers (SPs) compete for a common pool of customers ...
The i-band observing conditions at Dome A on the Antarctic plateau have been investigated using data acquired during 2008 with the Chinese Small Telescope ARray (CSTAR). The sky brightness, atmospheric extinction, cloud coverage and auroral appearance are obtained from these images. The median sky brightness of moonless nights is about 20.46 mag arcsec in the Sloan Digital Sky Survey (SDSS) i b...
