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...
Gas-phase deposition of pure acetonitrile at around 100 K provides an X-ray amorphous solid the molecular constituents of which are identified by far IR - spectroscopy as antiparallel dimers. On increasing the temperature two irreversible phase transitions - from the amorphous to the high temperature modification and from the high temperature to the low temperature modification - were observed below...
