assets.thermofisher.comThe infrared (IR) and Raman spectra of polyethylene and polypropylene are shown in Figures 1 and 2, respectively. Although both polyethylene and polypropylene are simple polyolefins, they can be readily identified and distinguished Figure 1: IR spectra of Polyethylene and Polypropylene. Figure 2: Raman spectra of polyethylene and polypropylene.
Measuring the Temperature of the Sky and Clouds - NASA
mynasadata.larc.nasa.govmeans that 1 meter away the thermometer “sees” a spot 1 meter across. For best results use an infrared thermometer with a look angle of at least 6:1. This means that 1 meter away the thermometer “sees” a spot 1/6 meter across. Many dierent kinds of IR thermometers are available from industrial suppliers and online dealers.

mmrc.caltech.eduInfrared Spectroscopy 251 Wavenumber 13,000–4,000 cm –1 4,000–200 cm –1 200–10 cm –1 This chapter focuses on the most frequently used mid IR region, between 4000 and 400 cm –1 (2.5 to 25 µm). The far IR requires the use of specialized optical materials and …
Infrared spectra of methanol, ethanol, and n-propanol
nvlpubs.nist.gov1. Introduction The infrared absorption spectrum of methanol in the vapor state was measured by Borden and Barker [l] l with a gratin g spectrometer. The stronger bands were resolved so that the rotational structure was apparen t. Their observations showed which band wei·e of the perpendicular and which were of the parallel type.
