  • The thermochromic and proposed visible photochromic properties of PDA-12,8 are examined by resonance Raman (RR) and Fourier transform infrared (FTIR) spectroscopies. The chromatic properties are derived from the conversion of a blue-colored PDA-12,8 material (produced upon ultraviolet-induced polymerization) to a red-colored material. Experiments are performed under well-controlled thermal conditions which aid in separating the ultraviolet polymerization used to generate the blue-colored polymeric material from its well-known thermochromic process and from photochromism proposed to be induced by visible radiation. For example, irradiation at 532 nm of water-cooled (0.5{degree}C) samples of the blue-colored material produces no chromatic changes. A chromatic change tomore » the red-colored material is induced by 532-nm radiation, however, when the PDA-12,8 is not cooled. No evidence supported a visible photochromic change in PDA-12,8 is found, and it is proposed that the previously reported chromatic properties derive from thermal effects. RR and FTIR data are presented which demonstrate that separate structural changes in the polydiacetylene backbone and in the hydrocarbon side chains of DPA-12,8 accompany the chromatic changes. RR results also show that no change occurs in the distribution of electron density along the PDA-12,8 backbone when chromatic effects are induced.« less
  • Temporal coherence of individual signal or idler beam, determined by the spectral correlation property of photon pairs, is important for realizing quantum interference among independent sources. Based on spontaneous four-wave mixing in optical fibers, we study the effect of chirp on the temporal coherence property by introducing a different amount of chirp into either the pulsed pump or individual signal (idler) beam. The investigation shows that the pump chirp induces additional frequency correlation into photon pairs; the mutual spectral correlation of photon pairs and the coherence of individual beam can be characterized by measuring the intensity correlation function g{sup (2)}more » of the individual beam. To improve the coherence degree, the pump chirp should be minimized. Moreover, a Hong-Ou-Mandel-type two-photon interference experiment with the signal beams generated in two different fibers illustrates that the chirp of the individual signal (idler) beam does not change the temporal coherence degree, but affects the temporal mode matching. To achieve high visibility among multiple sources, apart from improving the coherence degree, mode matching should be optimized by managing the chirps of individual beams.« less
  • Purpose: This work provides an interpretation of the chromatic properties of GafChromic™EBT3 films based on the chemical nature of the polydiacetylene (PDA) molecules formed upon interaction with ionizing radiation. The EBT3 films become optically less transparent with increasing radiation dose as a result of the radiation-induced polymerization of diacetylene monomers. In contrast to empirical quantification of the chromatic properties, less attention has been given to the underlying molecular mechanism that induces the strong decrease in transparency. Methods: Unlaminated GafChromic™EBT3 films were irradiated with a 6 MV photon beam to dose levels up to 20 Gy. The optical absorption properties ofmore » the films were investigated using visible (vis) spectroscopy. The presence of PDA molecules in the active layer of the EBT3 films was investigated using Raman spectroscopy, which probes the vibrational modes of the molecules in the layer. The vibrational modes assigned to PDA’s were used in a theoretical vis-absorption model to fit our experimental vis-absorption spectra. From the fit parameters, one can assess the relative contribution of different PDA conformations and the length distribution of PDA’s in the film. Results: Vis-spectroscopy shows that the optical density increases with dose in the full region of the visible spectrum. The Raman spectrum is dominated by two vibrational modes, most notably by the ν(C≡C) and the ν(C=C) stretching modes of the PDA backbone. By fitting the vis-absorption model to experimental spectra, it is found that the active layer contains two distinct PDA conformations with different absorption properties and reaction kinetics. Furthermore, the mean PDA conjugation length is found to be 2–3 orders of magnitude smaller than the crystals PDA’s are embedded in. Conclusions: Vis- and Raman spectroscopy provided more insight into the molecular nature of the radiochromic properties of EBT3 films through the identification of the excited states of PDA and the presence of two PDA conformations. The improved knowledge on the molecular composition of EBT3’s active layer provides a framework for future fundamental modeling of the dose–response.« less
  • We derive an expression for the magnetization {ital M}({ital k},{Delta}) in a pulsed-field-gradient experiment for spins diffusing in a confined space with relaxation at the pore walls. Here {bold k}={gamma}{delta}{bold g}, {delta}= pulse width, {bold g}= gradient strength, {gamma}= the gyromagnetic ratio, and {Delta} is the time between gradient pulses. We show that the deviation of {minus}ln({ital M}({ital k},{Delta})/{ital M}(0,{Delta})) from quadratic behavior in {ital k} in experiments in porous media can be a more sensitive probe of the microgeometry (size, connectivity, size distribution, shape, etc.), than either the enhancement of 1/{ital T}{sub 1} over the bulk water value, ormore » the macroscopic diffusion coefficient, which is derived from the slope of {minus}ln({ital M}({ital k},{Delta})/{ital M}(0,{Delta})) at small {ital k}{sup 2}, in the limit of large {Delta}. We propose some simple models of randomly oriented tubes and sheets to interpret the {ital k} dependence of the amplitude beyond the leading small-{ital k} quadratic behavior. When the macroscopic diffusion coefficient is unobtainable, due to the decay, the present considerations should be useful in extracting geometrical information. The effective diffusion constant derived from NMR exactly equals that derived from electrical conductivity only when the surface relaxivity is zero, but can be close to each other in favorable circumstances even for finite surface relaxivity. Exact solutions with partially absorbing boundary conditions are obtained for a slab and a sphere to infer that the normalized amplitude {ital M}({ital k},{Delta},{rho})/{ital M}(0,{Delta},{rho}) depends only {ital weakly} on the surface relaxivity {rho} for monodisperse convex-shaped pores in the parameter ranges of interest. We also obtain expressions for the mean lifetime of the amplitude in the geometries considered.« less
  • Generalized gradient approximations (GGA{close_quote}s) for the exchange-correlation energy improve upon the local spin density (LSD) description of atoms, molecules, and solids. We present a simple derivation of a simple GGA, in which all parameters (other than those in LSD) are fundamental constants. Only general features of the detailed construction underlying the Perdew-Wang 1991 (PW91) GGA are invoked. Improvements over PW91 include an accurate description of the linear response of the uniform electron gas, correct behavior under uniform scaling, and a smoother potential. {copyright} {ital 1996 The American Physical Society.}
