Diffuse Reflectance Spectra of V(CP)2 + on Silica

Diffuse Reflectance Spectra of V(CP)2 + on Silica

Diffuse reflectance spectra of vanadocene adsorbed on silica were recorded in the spectral region 4000-30 000 cm −1 . A d-d band around 13 000 cm −1 indicated, that vanadocene formed V(cp) 2 + on the support when the number of silanol groups was decreased. This cation is suggested to be stabilized b...

Zusammenfassung:Diffuse reflectance spectra of vanadocene adsorbed on silica were recorded in the spectral region 4000-30 000 cm −1 . A d-d band around 13 000 cm −1 indicated, that vanadocene formed V(cp) 2 + on the support when the number of silanol groups was decreased. This cation is suggested to be stabilized by the negative charge of deprotonated silanol groups.
