Examples are the introduction of lasers‚ Fourier transform (FT) Raman‚ charge-coupled device (CCD) detectors‚ confocal Raman spectroscopy and fiber-optics‚ that allowed conservation scientists to record molecular spectra of minute samples or directly from the art object.

Purpose The purpose of our lab was to reflux an isopentyl alcohol with carboxylic acid (acetic acid)‚ adding three drops of sulphuric acid acting as a catalyst to produce an ester (isopentyl acetate) and water. We verified our answers using infrared spectroscopy. Calculations for Percent Yield To find the percent yield we had to first find moles of our limiting reagent. 1) Weight of 5mL vial + cap

Water and Air Pollution Analysis Houston‚ Texas holds around two million people‚ carrying hundreds of thousands of cars daily on these busy freeways. On top of the pollutants coming from vehicles we also have the industrial refineries that are located only 45 minutes from the heart of Houston. Most the smog comes from the Houston Ship channel With the combination of these two things we can see how polluted our city and waters are. One of the main problems in Houston is air pollution.

of the central part of the galaxy. However‚ the first thing we need to do is to confirm the existence of a black hole at the galactic center by observation. There have been several explorations of black holes with a optical/infrared spectra‚ but the problem it that infrared spectra have a low frequency and a long wavelength which are absorbed by interstellar dust particles although the more active black holes contain more dust particles. For that reason it has been establish a better method using

Hunter partnered with DuPont to help CamelBak develop the Low Infrared Reflective (LIRR) system. 7. Other CamelBak innovations include the Water Beast reservoir‚ a fluid storage system that boasts 30 percent more rigidity than other packs on the market. 8.

Infrared telescopes are typically placed at the top of mountains‚ so that they are above most of the water molecules in the air. Ultraviolet telescopes are placed in space‚ since the majority of ultraviolet radiation does not penetrate the Earth ’s atmosphere (Hubblesite‚ 2015). Most infrared light is absorbed by the Earth ’s atmosphere‚ although some can be observed from very high elevations.
