Volume III/31 continues the compilation of nuclearquadrupole resonance spectroscopy data of solid substanceswhich started in with volume III/20 in1987 covering theliterature from the beginning of nuclear quadrupoleresonance spectroscopy in 1951 to 1982 and containing thedata for 8000 substances in the solid state, distributedamong threesubvolumes III/20 a, b, and c.Volume III/31 covers the literature publishedin the periodfrom the end of 1982 through the end of 1989. Included arethe data for substances studied for the first time, as wellas data for substances already present in the previousvolume III/20 if the data published there could be completedor improved by new studies. In total there are 2500substances in volume III/31, showing the scope andsignificance of nuclear quadrupole resonance spectroscopy upto recent times.The organization and representation of the data are the sameas in the previous volume III/20. A few, minor modificationsare explained in the introduction (chapter 1). Volume III/31can be consulted without recourse to its predecessor becausethe complete introduction and general tables are repeatedfrom III/20. The present subvolume III/31b completes thesupplementation.
