WebbHarrick Scientific Products specializes in designing and manufacturing instruments for optical spectroscopy. Since being established in 1969, Harrick Scientific has advanced the frontiers of optical spectroscopy through its innovations in all spectroscopic techniques. The basic principle of Raman optical activity is that there is interference between light waves scattered by the polarizability and optical activity tensors of a chiral molecule, which leads to a difference between the intensities of the right- and left-handed circularly polarised scattered beams. The spectrum of … Visa mer Raman optical activity (ROA) is a vibrational spectroscopic technique that is reliant on the difference in intensity of Raman scattered right and left circularly polarised light due to molecular chirality. Visa mer The field began with the doctoral work of Laurence D. Barron with Peter Atkins at the University of Oxford and was later further developed by Barron with David Buckingham at the University of Cambridge. More developments, … Visa mer Raman optical activity spectroscopy is related to Raman spectroscopy and circular dichroism. Recent studies have shown how by using Visa mer The symmetry of the neopentane molecule can be broken if some hydrogen atoms are replaced by deuterium atoms. In particular, if each methyl group has a different number of substituted atoms (0, 1, 2, and 3), one obtains a chiral molecule. The chirality in this case … Visa mer Due to its sensitivity to chirality, Raman optical activity is a useful probe of biomolecular structure and behaviour in aqueous solution. It has been used to study protein, nucleic acid, carbohydrate and virus structures. Though the method does not reveal … Visa mer Much of the existing work in the field has utilised custom-made instruments, though commercial instruments are now available. Visa mer • Linear dichroism • Magnetic circular dichroism • Optical activity • Optical isomerism Visa mer
