Symmetrical Analysis Phonon Modes of Crystal b-Ag8SnSe6
Journal Title: Фізика і хімія твердого тіла - Year 2015, Vol 16, Issue 2
Abstract
Symmetrical analysis of the phonon spectra of lowtemperature b-phase of crystal Ag8SnSe6 carried out. At the room temperature argyrodite Ag8SnSe6 belong to orthorhombic system with space group symmetry Pmn21. Classification of the main phonon modes of crystal carried out. Clarified selection rules for Raman spectra and infrared spectra.
