Herein, we demonstrate the use of 35Cl solid-state NMR (SSNMR) at moderate (9.4 T) and high (21.1 T) magnetic field strengths for the structural fingerprinting of hydrochloride (HCl) salts of active pharmaceutical ingredients (APIs) and several polym

The use of the univalent indium reagent [In([18]crown-6)][OTf] as a donor is investigated by its reactions with acceptors including InX(3) (X=Cl, Br, I). The donor-acceptor complexes of the form [X([18]crown-6)In-InX(3)] obtained in this manner repre

The acquisition of nuclear quadrupole resonance (NQR) spectra with wideband uniform rate and smooth truncation (WURST) pulses is investigated. (75)As and (35)Cl NQR spectra acquired with the WURST echo sequence are compared to those acquired with sta

Herein, we report the first detailed study of (209)Bi solid-state NMR (SSNMR) spectroscopy of extremely broad central transition powder patterns. (209)Bi ultrawideline SSNMR spectra of several bismuth-containing materials (bismuth oxyhalides, bismuth
Ultrawideline (137)Ba SSNMR spectra of several barium-containing systems (barium nitrate, barium carbonate, barium chlorate monohydrate, barium chloride dihydrate, anhydrous barium chloride, and barium hydrogen phosphate) were acquired at two differe
