Transmission versus reflectance spectroscopy for quantitation [PDF]
The objective of this work was to compare the accuracy of analyte concentration estimation when using transmission versus diffuse reflectance spectroscopy of a scattering medium. Monte Carlo ray tracing of light through the medium was used in conjunction with pure component absorption spectra and Beer-Lambert absorption along each ray's pathlength to ...

Constraining Exoplanet Mass from Transmission Spectroscopy [PDF]
Weighing Up Exoplanets The mass of a planet is important to know, but it is difficult to determine for an exoplanet. If a transmission spectrum of an exoplanet is available, de Wit and Seager (p. 1473 ) show that it is possible to determine its mass based on the properties of its ...
