✦ Synopsis

Abstract

We show that weak ^2^J(^71^GaO^31^P), typically ∼12 Hz in GaPO~4~, can be used to efficiently establish heteronuclear ^31^P^71^Ga correlation using a MAS HMQC experiment in gallo‐phosphate materials. The experiment demonstrated for cristobalite GaPO~4~ is then applied to Ga(PO~3~)~3~, where it allows the differentiation of the signature of three different Ga sites overlapping in the 1D spectrum.

## 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
