titanium dioxide spectroscopy

Millimeter-wave spectroscopy of titanium dioxide,

2011-7-1  Titanium dioxide, TiO 2, was the first triatomic transition metal dioxide investigated spectroscopically in the gas phase by both optical emission and infrared absorption spectra , . The low resolution of these studies prevented the determination of structural data beyond the conclusion that TiO 2 must be nonlinear.
