Broad-line nuclear magnetic resonance studies of the charge-transfer complexes of trimethylamine (NMe3) with iodine, bromine, and iodine monochloride indicate the presence of motion in the solid state. Trimethylamine itself was studied for purposes of comparison. The nature of the motional transitions for each species has been determined, and activation energies derived.

Diode matrices are given for an inexpensive decoder to deal with an output in Watts reflected code from a Hilger and Watts digitizer in an analogue-to-digital converter. One application is to the output of a broad-line nuclear magnetic resonance spectrometer.

Wide line nuclear magnetic resonance studies of pyridinium hexafluorophosphate, chloride, and nitrate show line width and second moment transitions which are attributed to reorientational motions of the pyridinium ring. The differences in transition temperatures are due to the different hydrogen bonded structures in the three salts.
