Abstract
•A simplified method to obtain derivative reflectivity spectra is described.•Van Hove singularities in electronic states of β-rhomb. B, B4.3C and YB66 are determined.•The results agree satisfactorily with interband transitions determined by other methods.
Differential reflectivity spectra of some icosahedral boron rich solids, β-rhombohedral boron, boron carbide and YB66-type crystals, were measured. The derivatives yield the van Hove singularities, which are compared with results obtained by other experimental methods.
