Formation of protonated orthoboric, metaboric and polyboric acids, and of their anions has been demonstrated in the gas phase by mass spectrometric techniques, which have been used to measure the proton affinity of H3BO3, 175.6 kcal mol–1, in fair agreement with the value of 181.2 kcal mol–1 from MO SCF ab initio calculations (1 cal = 4.184 J).
