Erratum to: Polymorphic phase transition in Superhydrous Phase B

the original publication of the article reported polarized FtIr spectra taken on oriented superhydrous phase B crystals. unfortunately, the authors mixed up the crystallographic cand a-axes during their measurement. the atomic coordinates for hydrogen H2 should be x = 0.45; y = 0.18; z = 0.27. thus, spectra in Fig. 10a are taken on the (001) plane with E parallel b (0°) and spectra in Fig. 10b are taken on the (010) plane with E parallel c (0°).
