For pt.I see ibid., vol.7, p.1588 (1974). The theory, developed in part I, of spectral line intensities emitted by plasmas in which a sound wave is propagating is extended to a consideration of their profiles. The expression that is presented for the profiles is based on the assumption that the spectral lines are broadened and shifted by the combined Doppler effects of motion associated with the sound wave and with thermal motion. The treatment covers isothermal and adiabatic sound waves in two plasma conditions, namely, (i) uniform low-density plasma; (ii) low-density plasma of uniform pressure and having a temperature gradient. The results show that the profiles have a characteristic asymmetric shape and that for a sound wave propagating towards the observer the centre of gravity of the profile is blue shifted although there is no net flow of plasma.
