## 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
## Abstract Carbon‐13 NMR relaxation data obtained for methyl groups in two dicyclohexane compounds were used to compare the Woessner and ‘model‐free’ approaches. It is shown that the extra flexibility offered by the latter leads to a more successful analysis of the data.
High-resolution 13C NMR spectra of 15 samples of uncomplexed and metalcomplexed tetranactin and nonactin were recorded in the solid state, revealing characteristic displacements of peaks due to complex formation and the effect of crystalline packing on the 13C chemical shifts and spidattice relaxati
