چکیده
The 1-phonon assisted non-radiative transfer in ruby is re-examined in the light of recent experimental results. It is shown that constructive (instead of destructive) interference among 1-phonon processes may occur.

Scalings of Inverse Energy Transfer and Energy Decay in 3-D Decaying Isotropic Turbulence with Non-rotating or Rotating Frame of Reference
Energy development of decaying isotropic turbulence in a 3-D periodic cube with non-rotating or rotating frames of reference is studied through direct numerical simulation using GPU accelerated lattice Boltzmann method. The initial turbulence is isotropic, generated in spectral space with prescribed energy spectrum E(κ)~κm in a range between κmin and ...
متن کاملApplication of Charge Transfer Complexation Reaction for the Spectroscopy Determination of Anticonvulsant Drug Primidone
The interaction of the perimidone drug in solution state with the σ-acceptor iodine, the aliphatic π-acceptor tetracyanoethylene (TCNE) and the aromatic π-acceptor 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ) have been studied through the initial formation of ionic intermediate to charge transfer (CT) complex in methanol at room temperature. The spectral studies of the complexes were determi...

متن کاملTemperature and Spectral Dependence of the Nonlinear Index of Ruby Via Nondegenerate Two Wave Mixing 6. AUTHORS
We have studied the nonlinear index of refraction of pink ruby between 565 nm and 610 nm using nondegenerate two wave mixing at 77 K and 294 K. Our new results support the model originally proposed by Venkatesan and McCall based on the large cross section of the transition from the Kramers doublets to the charge transfer band. In addition, we show that two-wave mixing can be used for accurate d...
متن کاملComparison of Benchtop Fourier-Transform (FT) and Portable Grating Scanning Spectrometers for Determination of Total Soluble Solid Contents in Single Grape Berry (Vitis vinifera L.) and Calibration Transfer
Near-infrared (NIR) spectroscopy was applied for the determination of total soluble solid contents (SSC) of single Ruby Seedless grape berries using both benchtop Fourier transform (VECTOR 22/N) and portable grating scanning (SupNIR-1500) spectrometers in this study. The results showed that the best SSC prediction was obtained by VECTOR 22/N in the range of 12,000 to 4000 cm-1 (833-2500 nm) for...
