Abstract : This report summarizes some seventeen papers published during the 1972-1975 period. The main part of the high dispersion spectral material used in the investigations is from Kitt Peak National Observatory, where staff members have kindly been allotted observing time. A high proportion of papers presented deal with the determination of abundances of chemical elements and isotope ratios. Several papers deal with the study of prominences and a couple with fast radio phenomena observed with radio spectrographs. Other items covered include stray light and disc emission lines in the CaII H- and K- line wings. (Author)
