Investigation of gaseous LiBO by Knudsen effusion mass spectrometry

Abstract

The reaction Li(g)+BO(g)=LiBO(g) has been studied by Knudsen effusion mass spectrometry. Heats of reaction ΔrH00 =(−332.5±5.0), (−317.4±5.0), and (−251.2±5.0) kJ mol−1 were determined for the linear structures Li–O–B and O–B–Li and for the bent structure (LiBO), respectively. These results are compared with values obtained theoretically.
