In accordance with the ambiguity noted above, some authors use the complex conjugate definition, where the ( still positive ) extinction coefficient is " minus " the imaginary part of \ underline { n }.
32.
The refractive index and extinction coefficient near the surface of the solid are perturbed by the returning strain pulses ( within the optical absorption depth of the probe light ), resulting in changes in the optical reflectance or transmission.
33.
Generally, FlAsH-EDT 2 has 0.1-0.6 fluorescence quantum efficiencies with several ?M detection limits for diffuse cytosolic tag and 30-80 extinction coefficients ( mM )-1 cm-1.
34.
Benzene has three aromatic ? ?! ? * transitions; two E-bands at 180 and 200 nm and one B-band at 255 nm with extinction coefficients respectively 60, 000, 8, 000 and 215.
35.
Even in isotropic media, so-called inhomogeneous waves can be launched into a medium whose refractive index has a significant imaginary part ( or " extinction coefficient " ) such as metals; these fields are also not strictly transverse.
36.
The refractive index ( " n " ) and extinction coefficient ( " k " ) are related to the interaction between a material and incident light, and are associated with refraction and absorption ( respectively ).
37.
They use considerably less energy in the laser, typically on the order of one extinction coefficient, backscatter coefficient, depolarization ), temperature, pressure, wind, humidity, trace gas concentration ( ozone, methane, nitrous oxide, etc . ).
38.
In general, an index of refraction is a complex number with both a real and imaginary part, where the latter indicates the strength of absorption loss at a particular wavelength & mdash; thus, the imaginary part is sometimes called the extinction coefficient k.
39.
UV-Vis spectrometers are used to measure the reflectance of light, and can be analyzed via the Forouhi-Bloomer dispersion equations to determine the Index of Refraction ( n ) and the Extinction Coefficient ( k ) of a given film across the measured spectral range.
40.
The compound provides real time near-infrared ( NIR ) fluorescence imaging with an extinction coefficient of 2.8 ?10 5 M " 1 cm " 1 and combinatorial phototherapy with dual photothermal and photodynamic therapeutic mechanisms that may be appropriate for adriamycin-resistant tumors.
