Optical phonons of small crystals
TL;DR: In this article, the long wavelength optical phonons of ionic crystals give rise to dipole-dipole forces, whose long range nature causes the vibrations to depend on the size and shape of the crystal sample.

Cluster Coordination and Photoluminescence Properties of alpha-Ag2WO4 Microcrystals
L. S. Cavalcante,Marcio Aurélio Pinheiro Almeida,Waldir Avansi,Ricardo L. Tranquilin,Elson Longo,Elson Longo,N. C. Batista,Valmor Roberto Mastelaro,M. Siu Li +8 more
TL;DR: The initial research to obtain hexagonal rod-like elongated silver tungstate (α-Ag(2)WO(4)) microcrystals by different methods and to study their cluster coordination and optical properties found them to have an orthorhombic structure.

Molybdena on titania: I. Preparation and characterization by Raman and Fourier Transform Infrared spectroscopy
Ka Yuen Simon Ng,Erdogan Gulari +1 more
TL;DR: In this article, the authors used Raman and Fourier Transform Infrared spectroscopy to follow the changes the catalysts underwent during the drying and calcination stages and found that the nature of the surface species depends on the loading, pH of the starting solution and the method of catalyst loading.
