optical rotation การใช้

• The optical rotation is known to be-81 degrees.
• Perucca reported that the dyed crystal did exhibit the desired optical rotation.
• Comparisons of calculated and experimental optical rotation was also used.
• A non-racemic mixture of two enantiomers will have a net optical rotation.
• An orthogonal probe beam detects the precession using optical rotation of linearly polarized light.
• The two differ in their optical rotation but they are identical in other physical properties.
• The optical rotation is proportional to the concentration of the optically active substances in solution.
• The rotation of light is measured using a polarimeter and is expressed as the optical rotation.
• The use of enantiomeric excess has established itself because of its historic ties with optical rotation.
• In particular, he made use of polarized light and studied optical rotation by various chemicals.
• The phenomenon described as " optical rotation " however, doesn't change that basic wave motion.
• His thesis was entitled " Research on the absorption and dispersion of light by substances capable of optical rotation ".
• One can monitor the mutarotation process over time or determine the equilibrium mixture by observing the optical rotation and how it changes.
• The other enantiomer ( optical rotation  " 42.73?) is found in small amounts in certain fungi and liverworts.
• One might expect the optical rotation to be small-- I can't find the exact number at the moment.
• Finally, optical rotation, 1 H NMR, and HRMS experiments of chemically synthesized bottromycin matched that of biologically produced bottromycin.
• The optical rotation of a given enantiomer of ketamine can vary between its chair conformation, but the orientation of the substituents varies.
• Moreover, the optical rotation of a compound may be non-linearly dependent on its enantiomeric excess because of aggregation in solution.
• The source gives some optical rotation data for the active forms ( zero for the others and DL mixtures, by experiment ).
• Specific rotation is an concentration of bulk sugar solutions is sometimes determined by comparison of the observed optical rotation with the known specific rotation.
