Abstract
The isotropic Raman spectra of liquid ammonia in the region around 3300 cm -1 , measured at 0, 21, 50, 75 and 100°C to a maximum of 2 k bars, were analysed using a model based on the projection-operator formalism. An analysis of the dependence of the parameters on temperature and density obtained from this model shows the particular influence of hydrogen bonding on the Raman band shape of liquid ammonia. The results obtained are compared with those obtained from the coupled oscillator model. Our investigations show that the values of the Fermi coupling and the unperturbed frequencies are dependent on the hypothetical intensity ratio of the unperturbed oscillators.
