Kim, BK Hamaguchi, H 2024-01-21T18:03:35Z 2024-01-21T18:03:35Z 2021-09-05 1997-10 0025-5408 https://pubs.kist.re.kr/handle/201004/143577 The Raman spectrum of O-18-labelled monoclinic Hafnia (HfO2) is reported. All of the eighteen Raman bands predicted from a group theoretical analysis are observed. The six Raman bands at 300-130 cm(-1) have little dependence on the O-18 content, whereas the remaining twelve Raman bands shift to low wavenumbers by the O-18-substitution. The former six are assigned to the Hf-Hf vibrations and the latter twelve are assigned to the Hf-O or O-O vibrations. Copyright (C) 1997 Elsevier Science Ltd.
