Carbohydrate NMR spectroscopy is the application of nuclear magnetic resonance (NMR) spectroscopy to structural and conformational analysis of carbohydrates.This method allows the scientists to elucidate structure of monosaccharides, oligosaccharides, polysaccharides, glycoconjugates and other carbohydrate derivatives from synthetic and natural sources.
Recent advances in this technique include the 1D-CSSF (chemical shift selective filter) TOCSY experiment, which produces higher quality spectra and allows coupling constants to be reliably extracted and used to help determine stereochemistry. TOCSY is sometimes called "homonuclear Hartmann–Hahn spectroscopy" (HOHAHA). [12]
Small-angle X-ray scattering (SAXS) is a small-angle scattering technique by which nanoscale density differences in a sample can be quantified. This means that it can determine nanoparticle size distributions, resolve the size and shape of (monodisperse) macromolecules, determine pore sizes and characteristic distances of partially ordered materials.

Two-dimensional projection of a hyperspectral cube. Hyperspectral imaging collects and processes information from across the electromagnetic spectrum. [1] The goal of hyperspectral imaging is to obtain the spectrum for each pixel in the image of a scene, with the purpose of finding objects, identifying materials, or detecting processes.
There are three different types of H atoms in ethyl acetate regarding NMR. The hydrogens (H) on the CH 3 COO− ( acetate ) group are not coupling with the other H atoms and appear as a singlet, but the −CH 2 − and −CH 3 hydrogens of the ethyl group (−CH 2 CH 3 ) are coupling with each other, resulting in a quartet and triplet respectively.

The foods within the bland diet are lower in fiber and fat, while also having a more neutral flavor and smell. These include:, Lean proteins prepared with little to no fat and with mild seasoning.
Images can be produced from a variety of methods including: microscopy, imaging probes, and spectroscopy. Fluorescence itself, is a form of luminescence that results from matter emitting light of a certain wavelength after absorbing electromagnetic radiation. Molecules that re-emit light upon absorption of light are called fluorophores. [1] [2]
