Biexciton Wavefunction in Bulk CuCl Probed by Inverse Polariton Series
Phys Status Solidi B Basic So, 2000
We report the observation of the radiative decay of excitonic molecules, selectively excited at the wavevector K m , into polaritons associated with the n 1s, 2s, 3s, and 4s states of the optically allowed Z 3 exciton in bulk CuCl. The K m dependence of the emission series (inverse polariton series) is quantitatively explained by the bipolariton model, leading to unambiguous estimation of the relative contributions of the 2s, 3s, and 4s exciton states to the four-particle molecule wavefunction, both in sign and in magnitude. The very structure of the molecule wavefunction is highly sensitive to the above relative contributions, and, in particular, we examine the Akimoto-Hanamura and hydrogen-molecule trial wavefunctions.

We report the temperature and magnetic-field dependences of Raman spectra in a distorted-triangular-lattice Ising-like antiferromagnet TlCoCl 3 . A broad Raman band from the continuous domain-wall pair excitations has been observed at 30 K. It is quantized in the Ne´el state and has been observed as a series of Raman peaks at 6 K. We also report the change of the phonon modes at the successive structural phase transitions. r
Theoretical description of the low-lying excited states of CuCl
Chemical Physics Letters, 1987
The low-lying excited states of CuCl have been investigated theoretically in the Hartree-Fock approximation. Spin-orbit interactions have been included semi-empirically using an atoms-in-molecules technique. All six excited states that were previously characterized experimentally are found to arise from fine structure sublevels of the Cu+ ( 3d94s 1.3D)CI-( 3p6 IS) configuration.

The reflectance spectra in the near UV spectral range close to the CuCl bandgap are modeled using a dielectric response function based on an exciton-polariton response with various models involving dead layers and reflected waves in the thin film. The exciton-polariton structure obtained is compared to other studies of bulk CuCl crystals. These different models are analyzed using a matrix-based approach and they yield theoretical spectra of reflected intensity. The fits provide parameter values which can be compared to bulk data known for CuCl and provide a nondestructive means of quantitative analysis of CuCl thin films. The best models are shown to match the experimental data quite well, with the closest fits produced when thin film front and rear interfaces are included. This model also accurately simulates the Fabry-Perot fringes present at energies lower than the Z 3 free exciton position in CuCl (at 3.272 eV). V C 2012 American Institute of Physics. [http://dx.
Surface-enhanced Raman scattering from chloride on copper electrodes
Chemical Physics Letters, 1993
A new method for the preparation of SERS active Cu electrode surfaces with high enhancement factors, which enable the observation of high quality spectra in the low-frequency region at different chloride concentrations, is proposed. Low-frequency modes at 160 and 145 cm-t are attributed to Cu-Cu vibrations by isotopic ("CU/~~CU) frequency shift. Qualitative agreement with predictions of the dipole-dipole coupling model are observed for Cu-Cl mode frequency dependence on Cl-ion concentra-
Calculation of excitation profiles from the vibronic theory of raman scattering
Chemical Physics, 1977
A se! of equations am presented for the calculation of excitation profJes of Raman lines. The equations are derived from third order perturbation theory using an improved basis set but may equally well be obtained by inclu~mg both Henberg-Teller and non-a~abaticv~r~nic ccmpliig in the standard equation for the Raman scattering tensor. A number of sample calculations are made of Raman excitation profiles which show the effects of the different types of coupling between states.
Direct calculation of electronic Raman scattering intensities in Cs2NaPrCl6
Journal of Physics Condensed Matter
The resonantly enhanced 266 nm excited electronic Raman spectrum has been recorded for polycrystalline Cs2NaPrCl6 at 10 K. Significant differences are observed in comparison with the 514.5 nm spectrum. These are rationalized by intensity calculations which, for the intermediate virtual excited (4f5d) states, utilize (I) the direct product of 4f1 core and 5d1 electronic states; (II) 4f5d coupled states obtained by using the Reid f2 and fd programs; (III) or for the initial and final (4f2) states, using the configuration-mixed wavefunctions (4f np) obtained by a configuration interaction assisted crystal field calculation. In general, the calculated trends in intensities are fairly similar (except where the calculated corresponding energy levels differ appreciably), showing that not only the interaction between the 5d electron and the (4f)1 core in the 4f5d configuration, but also the inclusion of the 4f np configuration, do not provide the dominant contributions to the electronic Ram...
