Volume III/48B continues the compilation of nuclear quadrupole resonance spectroscopy (NQRS) data of solid substances, covering the literarure from 1995 to the end of 2006. It provides 1265 NQRS data sets (measurement method, nucleus, temperature, quadrupole coupling constant, asymmetry parameter, resonance frequeny, remarks, references) for substances with Hill formulae ranging from C10H16 to Zn. 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 could be completed or improved by the new studies.
