Spin polarimetry

By using four detectors in a standard Mott detector, a single gold foil can be used for spin analysis along two orthogonal directions. The polarimeter depicted schematically in Figure 3.2.2.32 combines two Mott detectors, one oriented at 90° with respect to the other, allowing for complete three-dimensional spin polarimetry, that is, with quantization axes =x, y, and z [39]. 

Polarimetry of the brucine salts of L-guluronic acid and D-mannuronic acid released from alginates by acid hydrolysis has been used to measure the ratio of these acids in the native alginate. Nitroxide spin-labels have been investigated as molecular probes to determine the microviscosity of aqueous solutions of carbohydrates such as alginate. ...
