What do we mean by the F2g mode for YSZ/Zirconia in Raman Spectroscopy?

02 February 2016 1 9K Report

According, cubic Zirconia/YSZ shows a broad Raman peak centered at ~ 605 cm-1 corresponding to the F2g mode. I want to know the physical interpretation of the F2g mode

Thomas Mayerhöfer

A F2g mode is a threefold degenerated mode (hence the F), which is symmetric with regard to one of the fourfold rotation axis. The "g" shows that there is an inversion center which is kept during the vibration.

fatal error

When I tried to energy minimization my system, I got fatal error as below. Fatal error: Atomtype opls_116 not found Although I've already added this line: ; include water #include "oplsaa.ff/spc.itp" to [molecultype] directive in my topology.

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...
