dc.description.abstract	The extraordinarily wide 22 GHz emission from W49A and two other galactic HI1 regions is discussed, and arguments presented why the entire width of these spectra cannot be attributed to the 616 → 523 transition of H2O. It is suggested that most of the weak emission with large frequency shifts is due to stimulated Raman scattering of the strong central features appearing at the expected frequency of the water vapour line. It has not been possible to identify the scattering agent, but it is predicted that the spectra of millimetre-wave maser sources should also show such freqency-shifted features.	en
