摘要：

Nitric acid dihydrate (NAD), which may be an important constituent in polar stratospheric clouds, has been investigated by infrared and Raman spectroscopy. Spectral changes, upon variation in temperature and concentration, have been analysed in detail and interpreted as a phase change between a low- and a high-temperature modification. This interpretation was corroborated by the results of a previous X-ray diffraction (XRD) study of samples prepared under essentially the same conditions. The present FTIR spectra are compared to literature data. (C) 2003 Elsevier B.V. All rights reserved.
