Abstract
The infra-red spectra of the anhydrous and octahydrated rare-earth carbonates have been recorded as potassium bromide disks in the region 4000–250 cm −1 and are discussed in the light of known crystallographic evidence for their structures. The spectra of the products formed by heating the anhydrous carbonates to 470°C were similarly recorded in an attempt to find out if either the monoxydicarbonate or the dioxymonocarbonate were formed. The spectra of the rare-earth sesquioxides are also reported.
