摘要: Abstract The resonance Raman spectra of K 2 (Ti(O )(SO 4 ) )·5H O and )(C )·3H are recorded. results consistent with the triangular structure peroxotitanium unit, Ti(O ), C 2ν symmetry. ν(OO), ν s (TiO) as observed around 890, 610 535 cm −1 , respectively. effects shown to be associated 425 nm absorption band. This band is assigned 2− → Ti(IV) charge-transfer transition. calculated force constant values for TiO bonds 320 275 N m
