Mid-Infrared and Near-Infrared Diffuse Reflectance Spectroscopy for Soil Carbon Measurement

Diffuse reflectance spectroscopy offers a nondestructive means for measurement of C in soils based on the The ability to inventory soil C on landscapes is limited by the reflectance spectra of illuminated soil. Both the NIR ability to rapidly measure soil C. Diffuse reflectance spectroscopic (400–2500 nm) and MIR (2500–25 000 nm) region have analysis in the near-infrared (NIR, 400–2500 nm) and ...

The Mid-infrared Emission of Local Luminous Infrared Galaxies

In this paper we use the complementary imaging capabilities of Spitzer (sensitivity) and Gemini-South/TReCS (spatial resolution) to study the mid-IR properties of local (d < 75Mpc) LIRGs. The T-ReCS 8− 10μm imaging observations of LIRGs have allowed us to spatially resolve the nuclear emission (star formation and/or AGN) and that of H ii regions in the central 3−7 kpc regions of LIRGs. From the...

Planar array infrared emission spectroscopy.

Planar array infrared spectroscopy (PA-IR) is shown to be a powerful new approach to infrared emission spectroscopy (IRES). A proof-of-concept study of selected polymers indicates that PA-IRES allows acquisition of emission spectra with a high signal-to-noise ratio at temperatures as low as 80 degrees C. It is shown that a time resolution below 20 ms is readily achievable for time-resolved char...

Mid - Infrared Emission Features in Wl 16

We present long-slit 7.5–13.5 mm spectra of WL 16, a Herbig Ae star in the r Ophiuchi dark cloud that is surrounded by a ∼1000 AU diameter infrared-emitting nebula. Mid-IR emission features are detected in every region of the nebula from center to edge, and the underlying continuum color temperature is approximately 10 times hotter than would be expected from large grains in thermal equilibrium...
