Laser raman spectra for solid and liquid states of hopeite crystal films.

Resonant Raman spectra of diindenoperylene thin films.

Resonant and preresonant Raman spectra obtained on diindenoperylene (DIP) thin films are interpreted with calculations of the deformation of a relaxed excited molecule with density functional theory (DFT). The comparison of excited state geometries based on time-dependent DFT or on a constrained DFT scheme with observed absorption spectra of dissolved DIP reveals that the deformation pattern de...

The vibrational Raman spectra of purified solid films of CbO and CT0

Profiling of liquid crystal displays with Raman spectroscopy: preprocessing of spectra.

Raman spectroscopy is applied for characterizing paintable displays. Few other options than Raman spectroscopy exist for doing so because of the liquid nature of functional materials. The challenge is to develop a method that can be used for estimating the composition of a single display cell on the basis of the collected three-dimensional Raman spectra. A classical least squares (CLS) model is...

The crystal structures and Raman spectra of aravaipaite and calcioaravaipaite

The original structure determination for aravaipaite, Pb3AlF9(H2O), indicated it to be monoclinic, P21/n, with a = 25.048(4), b = 5.8459(8), c = 5.6505(7) Å, β = 94.013(3)°, V = 829.7(2) Å3, and Z = 4. Examination of additional crystal fragments from the same specimen revealed that some have a triclinic cell, P1, with a = 5.6637(1), b = 5.8659(1), c = 12.7041(9) Å, α = 98.725(7)°, β = 94.020(7)...

Infrared and polarized Raman spectra of dixanthinium tetrachlorozincate single crystal

Single crystal dixanthinium tetrachlorozincate has been grown from dilute chloridric acid. Polarized Raman spectrum of the single crystalline sample, FT-Raman and FT-IR spectra of the polycrystalline samples have been examined and the bands assigned to the appropriate modes predicted by a factor group analysis for the space group Pmn21. The crystal structure has been confirmed by powder XRD mea...
