The Raman spectrum of vaterite prepared by electrochemical scaling in carbonically pure water is presented and analysed following the rules of group theory. It is shown that only one of the three crystallographic determinations already proposed for the structure of vaterite is compatible with the results obtained. Then it is shown that the formation of aragonite on a vaterite crystal is a transformation of the vaterite structure and not a further crystallization of this polymorph upon vaterite crystals.
