In a series of polymethoxy benzaldehydes and acetophenones it was found that diorthosubstitution distorts the Ar-OCH3 conformation. This distortion is accompanied by a downfield shift in the corresponding methoxyl 13C frequencies and an increase in their spin-lattice relaxation times.

Nuclear magnetic resonance of 13C is used to probe the overall and internal motions of proline. Spin-lattice relaxation times (TI) are reported for proline monomer dissolved in water/glycerol mixtures. Rates of overall molecular motion and internal motion depend on solvent composition but to differe

## Abstract ^13^C spin–lattice relaxation times (__T__~1~'s) are reported for C‐3 of 2‐methylindole (methyl,3‐^13^C~2~) as a function of the concentration of added 1,3,5‐trinitrobenzene at 35°C in 1,2‐dichloroethane. The observed decreases in __T__~1~, with increasing concentrations of 1,3,5‐trinit

## Abstract A pulse sequence is presented which allows measurement of short __T__~1~ values (< 1 s) in solids, avoiding probe damage by the use of saturating sequences of 90° pulses. The use of the sequence is illustrated for a cross‐linked polymeric system which contains composite peaks having bot
