## Abstract ^13^C CP/MAS NMR spectra were recorded to characterize the solidβstate conformation of flavonoids: galangin, kaempferol, quercetin, myricetin, chrysin, apigenin, luteolin, acacetin, hesperetin and naringenin. Correct assignment of the signals in solutionβstate spectra (using APT, HSQC a
A method for temperature calibration of CP/MAS NMR probes and their temperature controllers is described that relies upon known phase changes in the compounds adamantane, d-camphor, pivalic acid and DABCO. The method appears to give a convenient and reliable calibration over the temperature range cu
