1) Because Fe S+ needs the neighbourhood of alkali ions for charge compensation for its different coordJnations, these alkali metals directly participate in the structure of the

As already remarked, many of the iron lines in the infra-red are susceptible to pressure broadening and have line profiles with a significant Lorentzian component; this is
