Description
Summary:[Display omitted] •The mineral tengerite-(Y) has been studied by vibrational spectroscopy.•Multiple carbonate stretching modes support the concept of non-equivalent carbonate units.•Intense sharp bands at 464, 479 and 508cm−1 are assigned to YO stretching modes.•Multiple Raman and infrared bands in the OH stretching region are observed. The mineral tengerite-(Y) has been studied by vibrational spectroscopy. Multiple carbonate stretching modes are observed and support the concept of non-equivalent carbonate units in the tengerite-(Y) structure. Intense sharp bands at 464, 479 and 508cm−1 are assigned to YO stretching modes. Raman bands at 765 and 775cm−1 are assigned to the CO32− ν4 bending modes and Raman bands at 589, 611, 674 and 689cm−1 are assigned to the CO32− ν2 bending modes. Multiple Raman and infrared bands in the OH stretching region are observed, proving the existence of water in different molecular environments in the structure of tengerite-(Y).
