The 11B nuclear magnetic resonance spectra of sodium, potassium and ammonium polyborates in aqueous solutions, - as a function of concentration and pH - , provide information of the hydrolysis equilibria. Two 11B NMR lines are observed in aqueous solutions of Na[B5O6(OH)4], K[B5O6(OH)4] and NH4[B5O6(OH)4]. Only one 11B NMR line is recorded in aqueous solutions of (NH4)2[B4O5(OH)4] and Na2[B4O5(OH)4]. The results of the 11B NMR spectra are discussed and compared with the results obtained from Raman studies of aqueous polyborate solutions

Chemical shift data and conductivities of acetylacetonates of some group IA, IIA, and IIIA metals in dimethylsulfoxide are recorded. It is concluded that nuclear magnetic resonance spectra cannot give definite information on π-bonding in these complexes, though the results for the group III elements are consistent with the presence of such bonds, as is the evidence from related spectroscopic studies.
