Reflectance spectroscopy is a rapid and non-destructive method that can be used to detect organic compounds in geologic samples over a wide range of spatial scales that includes outcrops, hand samples, drill cores, and planetary surfaces. In order to assess the viability of this technique for quantification of organics and aliphatic compounds in particular, the present study examines how clay m...

The present experiments were conducted to develop an optimal protocol for visible and near-infrared reflectance spectroscopic evaluation of meat quality. It was determined that spectra were more repeatable using a 35 mm-diameter high-intensity reflectance probe rather than a 3 mm-diameter reflectance probe. Using the high-intensity reflectance probe, spectra were generally very repeatable (e.g....

Soil reflectance spectroscopy is a well-known technique to assess soil properties rapidly and quantitatively in both point (spectroscopy) and spatial (imaging spectroscopy (IS)) domains. The quantitative approach has been developed in the past two decades by many researchers, with much literature on the topic. Basically, this approach was adopted from other disciplines (e.g. food, textiles), wh...

[1] Reflectance spectroscopy of outer solar system bodies provides direct observations for interpreting their surface compositions. At Titan, the Cassini spacecraft revealed dark patches in the surface reflectance at 2 and 5 mm, interpreted as hydrocarbon lakes forming seasonally through a methane cycle. Whereas the composition of planetary materials in the solar system has been inferred from c...

The goal of this study was to characterize the changes in biomass with torrefaction for near infrared reflectance (NIR) and attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectroscopy for sweetgum, loblolly pine, and switchgrass. Calibration models were built for the prediction of proximate analysis after torrefaction. Two dimensional (2D) correlation spectroscopy between NI...
