Matrix isolation studies on ytterbium dichloride : a non-linear molecule. Observation of isotopic structure on ν1 and ν3
Abstract
Studies of the infrared spectrum of ytterbium dichloride isolated in an argon matrix demonstrate that the molecule is non-linear. On the basis of chlorine isotope shifts and the relative intensities of ν1 and ν3 the bond angle is estimated to be 126 ± 5°.
