Absolute measurement of the optical polarizability of C 60
نویسنده
چکیده
We report on a new optical technique that uses light forces and a time-of-flight spectrometer to make absolute measurements of cluster polarizabilities. This is also the first accurate report of an ac polarizability measurement of a condensable cluster in the gas phase. We have determined the optical polarizability of C60 at the fundamental wavelength of a Nd:YAG laser ~1.064 mm! to be a57964 Å. © 2000 American Institute of Physics. @S0021-9606~00!01038-2#

A study of energy gap, refractive index and electronic polarizability of ternary chalcopyrite semiconductors
A simple relation between the optical electronegativity, energy gap, refractive index and electronic polarizability is given for ternary chalcopyrite semiconductors. Energy gap has been evaluated from the optical electronegativity whereas refractive index and electronic polarizability values have been evaluated from the energy gap by proposing a linear relation between them. The calculated valu...
متن کاملExperimental and phenomenological aspects of circular birefringence and related properties in transparent crystals∗
Here, we review the history, theory, measurement technique and experimental results on gyrotropic phenomena including optical rotation (optical activity), electrogyration, the Faraday effect and magneto-electrogyration in transparent crystals, including examples of structural phase transitions. Relations to the absolute structure are discussed and model calculations are performed on the basis o...
متن کاملOptical Properties of Some Oligothiophene Derivatives: DFT Study
Polythiophenes are of considerable interest as synthetic metals. The optical properties of polythiophenes can be easily affected by alkyl chain or other side groups to the thiophene ring. The effect of polymerization degree on the energy gap was studied in the case of polythiophene as a conjugated polymer at B3LYP/6-31+G(3d,3p) level of theory. Up to n = 16 could be confident that this degree o...

متن کاملRaman Spectra of a PMMA Microstructured Optical Fibre and Direct Measurement of Its Gain Coefficient
A polymethylmethacrylate (PMMA) microstructured polymer optical fiber (mPOF) is fabricated and characterized. Using the cut-back technique the fiber loss is measured which is higher than the step-index silica fibers. Through a novel experimental scheme, the backward Stokes spectrum of the fabricated mPOF is recorded over a range exceeding 3000 cm‑1 during the cut-back method and compared ...
