Determination of Molybdenum - Oxygen Bond Distances and Bond Orders by Raman Spectroscopy
نویسنده
چکیده
A correlation is developed for relating Rarnan stretching frequencies of molybdenum-oxygen ( M 4 ) bonds to their respective bond distances in molybdenum oxide compounds. M+O bond orders are also related to Stretching frequencies. The M 4 correlation is expected to offer invaluable insight into the structures of rnolybdate species in chemical systems which are not amenable to analysis by difkaction or other spectroscopic techniques. In the present study, the correlation is used to jwedict stretching frequencies for perfect MOO, and MOO, structures, and to determine Mo-0 bond distances of the MOO, octahedron in Ba,CaMoO, as well as the dehydrated surface molybdate species in MoO,/AI,O,.

Determination of niobium-oxygen bond distances and bond orders by Raman spectroscopy
An empirical correlation is established for relating Raman stretching frequencies of niobium-oxygen (Nb-O) bonds to their respective bond distances in niobium oxide compounds. The correlation is an exponential least-squares fit between measured Raman frequencies and reported crystallographic bond lengths. Niobium-oxygen bond strengths (in valence units) are also related to Raman stretching freq...

A new method is presented for interpreting the Raman spectra of bismuth oxides. The method relies on empirical relations between bismuth-oxygen (Bi-0) bond lengths, bond strengths, and Raman stretching frequencies. A least-squares exponential fit of crystallographically determined Bi-0 bond lengths and Raman stretching frequencies is presented along with a relation between Bi-0 bond strengths, ...

متن کاملEffect of Thickness on the Structural Properties of Tellurium Film Prepared by Thermal Evaporation
In this research, tellurium (Te) film with thicknesses of 100-250 nm were deposited on ceramic substrates by thermal evaporation at 373 K. The thickness of the film was determined by Rutherford backscattering spectroscopy. The influence of the thickness on the structural, morphological and molecular bonds was characterized using XRD, scanning electron microscope, and Raman spectroscopy. The XRD...
