Applying the above formula: Glucose[α]D20=0.1047×1002×0.1=52.4° Fructose[α]D20=−0.1824×1002×0.1=-91.2° Typically, the concentration of a solute is calculated by measuring the rotation angle [α] of this solute at 20°C, hence: C(g/100mL)=α×100[α]D20×l In the case ...

The spin angular momentum (SAM) plays a significant role in light-matter interactions. It is well known that light carrying SAM can exert optical torques on micro-objects and drive rotations, but 3D rotation around an arbitrary axis remains challenging.
Re: prediction of optical rotation «Reply #2 on:July 26, 2018, 10:11:59 PM » Thanks for the reply. I do not remember having read anywhere about this kind of calculation . Yes S-cis and S-trans would make it little more complicated. It would be interesting to find out that som...
Novel and practical approaches for harvesting light for particle rotation have since been demonstrated, where the structure is always subjected to a positive optical torque along a certain axis if the incident angular momentum has a positive projection on the same axis. We report here an interesting...
The rotation axes are defined by the corresponding SAM1, SAM2, and SAM3 in (b). arbitrary axis by the vectorial transfer of SAM to the particles. To this end, we construct a theoretical formula that relates the 3D SAM vector of a tightly focused field to the local polarization helicity...
From the above formula, n and k are the basic optical parameters that determine the transmittance of the material. The determined spectral transmittance of the material at the same thickness is obtained by calculation. Fig. 6 compares each of the six 20 μm polymers materials, whose ...
In the gain calculation, since the photocurrent measured by the photodetector is proportional to the optical power, the RF power will be proportional to the square of the received optical power. Therefore, one dB of RF power change corresponds to 0.5 dB change in the EDFA optical gain. Using...
Optical Rotation Optical Rotation is the twisting of plane-polarized light. The sugar solution displayed an Optical Rotation of +30°. 8 Specific Rotation Specific Rotation uses a mathematical formula for calculation. The Specific Rotation was calculated using the observed rotation, path length, and ...
As illustrated in Figure 1, only part of the beam needs to be rotated, so the components that need to be rotated do not use the same formula as the rest of the components. This implies that in the region of the beam depicted in Figure 1 that has undergone rotation, there exists a ...
