Raman scattering and structural properties of MoO3

Harvesting, Storing and Utilising Solar Energy using MoO3: Modulating Structural Distortion through pH Adjustment

“…[14,15] Raman spectroscopy is an essential tool to elucidate local distortions of MoO 6 octahedra introduced by O vacancies in a-MoO 3 . The assignment of different modes and lattice vibrations for a-MoO 3 thin films synthesised in this work follows the single-crystal study and valence force-field calculation by Py et al [16] The structural description of a-MoO 3 can also be described alternatively as a layered structure constructed from infinite chains of corner-linked MoO 4 tetrahedra along the (001) direction as depicted in Figure 1 d. Each layer of a-MoO 3 comprises two halflayers that interact weakly. [16] Adjacent layers are then linked in a parallel fashion along the (010) net-plane and connected by weak van der Waals forces.…”

Vibrational Spectroscopy

“…The assignment of the bands was based on results of a single-crystal study and valence force field (VFF) analysis by Py and coworkers [177,178], in which the structure of MoO 3 proposed by Kihlborg [175] (see Fig. 5) was used.…”

Electrochemical properties of nanofibers α-MoO3 as cathode materials for Li batteries

“…The spectral fingerprints of the a-phase are clearly seen in these Raman spectra, which can be analyzed using the orthorhombic D 2h 16 symmetry. The assignment of the different modes and lattice vibrations can be made according to[22]. It is reported inTable 1.…”
