Bonding in the hexagonal, cubic (zincblende), rhombohedral, and wurtzite phases of boron nitride was characterized using core-level photoabsorption. In the boron and nitrogen 1[ital s] photoabsorption cross section we observed resonances that were unique to each of the phases and that were associated with the [ital sp][sup 2] or [ital sp][sup 3] bonding present. These spectroscopic standards were then used to characterize the bonding and morphology in an incoherent thin film of BN based on its core-level photoabsorption. The film studied had predominantly [ital sp][sup 2] (hexagonal-like) bonding with some evidence of [ital sp][sup 3] (cubic-phase) bonds.
