## Abstract Gel networks prepared from aqueous melamine‐formaldehyde resins via a sol–gel route were characterised by ^13^C CPMAS (where MAS stands for magic angle spinning)‐NMR and __T__~2~ relaxation. We show that within the aqueous networks, the type and amount of functional groups on the melami

## Abstract A combination of solid‐state ^13^C CP/MAS NMR methods was used to study the rates of rotation of the phenyl group in 3,5‐dimethyl‐1‐phenylhex‐1‐yn‐3‐ol. The methods used were __T__~1ρ~ measurements, lineshape analysis and 2D exchange spectroscopy over the temperature range 219–284 K. Th
