摘要：Lithium monoxide anion (LiO-) has been generated in the gas phase and is found to be a stronger base than methyl anion (CH[IMG]f1.gif" ALT="Formula" BORDER="0">). This makes LiO- the strongest base currently known, and it will be a challenge to produce a singly charged or multiply charged anion that is more basic. The experimental acidity of lithium hydroxide is {Delta}H{degrees}[IMG]f2.gif" ALT="Formula" BORDER="0"> = 425.7 {+/-} 6.1 kcal{middle dot}mol-1 (1 kcal = 4.184 kJ) and, when combined with results of high-level computations, leads to our best estimate for the acidity of 426 {+/-} 2 kcal{middle dot}mol-1.
