In order to test this hypothesis and determine an appropriate structural model for solution-deriyed lithium borate networks (gels), Brinker et al. performed FTIR investigations of crystalline alkali borates and partially hydrated crystalline alkali-borates (with N4 = 0.25 to 0.50). A prominent spectral feature (see, e.g.. Fig. 37a) of the anhydrous tetra- and triborate compounds is the 1260-cm vibration due to oxygens bridging between trigonal borons contained in separate primary units [183] (Fig. 38a). Anhydrous lithium diborate is composed exclusively of diborate units linked by oxygens bridging between 3- and 4-coordinated borons and exhibits no 1260-cm vibration [185]. Partial hydrolysis of the tetra- (and triborates) causes a dramatic reduction in the relative intensity of the 1260-cm vibration (Fig. 37b).
