Transient infrared emission spectroscopy

Analytical Chemistry, 1989
Transient Infrared Emission Spectroscopy (TIRES) is a new technique that reduces the occurrence of self-absorption in optically thick solid samples so that analytically useful emission spectra may be observed. Conventional emission spectroscopy, in which the sample is held at an elevated, uniform temperature, is practical only for optically thin ...

Aurorally enhanced infrared emissions

Applied Optics, 1979
Aurorally enhanced IR emissions in the 2.9-microm region have been measured from a jet aircraft with a zenith looking radiometer. Overtone chemiluminescent emission from chemically produced NO is the postulated source.

Planar Array Infrared Emission Spectroscopy

Analytical Chemistry, 2007
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.

Infrared emission spectroscopy

2001
A review is made of the instruments and of the observation modes that are used for the study of the Earth's atmosphere with emission spectroscopy. A short comparison is made between heterodyne and optical techniques and details are provided of the second technique with a few examples of real instruments.

Infrared Emission Spectroscopy

1995
A molecule in a vibrationally excited state has a certain probability of emitting infrared radiation in the presence or in the absence of incident electromagnetic radiation, resulting in induced and spontaneous emission, respectively. At room temperature (T ≃ 300K), the number of molecules in a first excited state is less than 1% of the population in ...

Infrared emissivity of burn wounds

Clinical Physics and Physiological Measurement, 1992
Emissivities of burn wounds and tissue samples have been measured in the wavelength range 8-14 microns using a non-contact method. Emissivities of wound tissues studied were in the range 0.976-0.992, greater than those of intact skin by 0.01-0.03. This will result in underestimates of the difference in temperature between wounds and normal skin of 0.1 ...
