The vibrational spectrum of Mg2.5VMoO8 obtained by quantum mechanical simulation is compared with the experimentally observed Raman spectrum. This simulation suggests that the observed band at 1016 cm(-1) is attributed to the Mo=O-Mg stretching from two-coordinate oxygen atoms that are adjacent to Mg2+ cation vacancies. Extended X-ray absorption fine structure spectroscopy supports the structur...

Raman spectroscopy is based on analysis of inelastically scattered light. This technique has a wide range of uses in chemistry, solid-state physics and other fields. Raman spectroscopy can distinguish between molecules and can identify them by their characteristic spectra. In this seminar I will discuss instrumentation required for Raman spectroscopy in medical applications, followed by specifi...

This project investigated the potential application of two spectral approaches hyperspectral imaging in the near infrared (NIR) region and Raman spectroscopy to predict meat quality. Predictions of meat quality included Warner-Bratzler shear force (WBSF), consumer assessed eating quality and fatty acid profiles. In addition, the relationship between WBSF values and sensory acceptability was eva...

The optical spectrum of reduced myeloperoxidase (EC 1.11.1.7) displays an unusual red shift of the Soret band which is at 472 nm and the alpha-band which is at 636 nm. The spectral properties of myeloperoxidase can be modified by means of acid treatment. Upon short exposure to acid (pH 1.7) the red-shifted optical absorption spectrum of the reduced enzyme (lambda max at 472 nm) was blue-shifted...
