W(CO)6 in cryogenic solids: A comparative study of vibrational properties.

A comparative study of the vibrational properties of W(CO) 6 has been performed in different solids at cryogenic temperatures focusing on the IR absorption and the vibrational dynamics of the CO stretching mode of the organometallic compound. Guest-host interactions are investigated in doped solids through the linear IR spectroscopy and four-wave mixing techniques at different temperatures. We show how the host nature, the trapping site, the crystallographic ordering affect the properties of the guest molecule and in particular its vibrational dynamics. [ABSTRACT FROM AUTHOR]
