Raman spectra of glassy lithium tetraborate activated with terbium oxide of various concentrations were investigated. Most of the observed structure in the Raman spectra of the Li2B4O7: Tb2O3 glass is due to mixed vibrations of complex boron- and terbium-oxygen complexes which are typical to a superposition of tetragonal Li2В4О7 and cubic Tb2О3 structures.

<p>One sample of 1D bundle of cellulose microfibrils in the form of lignified flax fibre (0.10526 mm x 10 mm), and one 2D networks of cellulose microfibrils in the form of tunicate cellulose (0.07 mm x 5 mm x 10 mm), bacterial cellulose (0.135 mm x 5 mm x 10 mm) and microfibrillated cellulose (0.08 mm x 5 mm x 10 mm) were put on a glass slide parallel to the principal spectrometer axis. Raman spectra were measured all round in-plane under both half (in 5° steps) polarisation from 0° to 360° in extended mode between 100 cm<sup>-1</sup> and 1150 cm<sup>-1</sup> in 3 accumulations at 10s exposure and 100% laser power. The cursor was placed at the peak of the 1095 cm<sup>-1</sup> band, and intensity read.</p>

Ir And Raman

Abstract Failure analysis of organics at the microscopic scale is an increasingly important requirement, with traditional analytical tools such as FTIR and Raman microscopy, having significant limitations in either spatial resolution or data quality. We introduce here a new method of obtaining Infrared microspectroscopic information, at the submicron level in reflection (far-field) mode, called Optical-Photothermal Infrared (O-PTIR) spectroscopy, that can also generate simultaneous Raman spectra, from the same spot, at the same time and with the same spatial resolution. This novel combination of these two correlative techniques can be considered to be complimentary and confirmatory, in which the IR confirms the Raman result and vice-versa, to yield more accurate and therefore more confident organic unknowns analysis.
