Volume III/39 continues the compilation of nuclear quadrupole resonance spectroscopy data of solid substances which started in with volumes III/20 and III/31. The literature from the beginning of nuclear quadrupole resonance spectroscopy in 1951 to 1996 is covered. Included are the data for substances studied for the first time, as well as data for substances already present in the previous volumes if the data published there could be completed or improved by new studies. In total there are more than 10.000 substances in the volumes, showing the scope and significance of nuclear quadrupole resonance spectroscopy up to recent times. A few, minor modifications are explained in the introduction (chapter 1). Volume III/39 can be consulted without recourse to its predecessor because the complete introduction and general tables are repeated from III/20 and III/31.
