The present Landolt-Bornstein volume III/48A continues the compilation of nuclear quadrupole resonance spectroscopy (NQRS) data of solid substances which started with volume III/20 (covering the literarure from the beginning of NQRS in 1951 through to 1982), volume III/31 (1982-1989), and volume III/39 (1989-1995), to the end of the year 2006. Volume III/48A provides 1270 NQRS data sets (measurement method, nucleus, temperature, quadrupole coupling constant, asymmetry parameter, resonance frequeny, remarks, references) for substances with Hill formulae ranging from Ag to C10H15. The solids considered are composed of pure chemical elements, inorganic or organic compounds, as well as intermolecular compounds, hydrates, etc., and are arranged in alphanumeric order of the molecular formula expressed according to the Hill system. Included are the data for substances studied for the first time, as well as data for substances already present in previous volumes if the data published there...
