Spectral Properties of Anhydrous Carbonates and Nitrates
Earth and Space Science, 2021 The spectral properties of anhydrous carbonates and nitrates are dominated by strong, sharp vibrational bands due to the CO32− and NO3− anions observed as absorption bands in near‐infrared spectra, as Reststrahlen features or absorption bands in mid‐IR ...
