"Low-Frequency Raman Spectra of Nitric Acid Hydrates";

Kurzfassung englisch:
Raman spectra of solid nitric acid hydrates (NAM, a- and ß-NAD, a- and ß-NAT, and NAP) are obtained
in the low-frequency region 20-175 cm-1 where phonon bands show characteristic patterns. This fingerprint
information, intimately related to the structure and symmetry of the unit cell, is well suited for observation
of phase changes in solid nitric acid hydrates and allows the distinction of mixtures of different hydrate
phases. The low-frequency spectra are correlated with the spectra of the respective symmetric NO stretching
vibration (1000-1080 cm-1), with literature data, and with X-ray diffraction patterns.
