INFRARED SPECTROSCOPY: FUNDAMENTALS AND APPLICATIONS Barbara H. Stuart University of Technology‚ Sydney‚ Australia 72 Infrared Spectroscopy: Fundamentals and Applications hydrocarbons appear in the 3000–2800 cm−1 range and the C–H stretching bands of methyl groups and methylene groups are readily differentiated. For methyl groups‚ asymmetric C–H stretching occurs at 2870 cm−1 ‚ while symmetric C–H stretching occurs at 2960 cm−1 . By comparison‚ methylene groups show asymmetric stretching at 2930

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. Case study Red pigment samples were collected from the early Christian necropolis of El-Bagawt at Kharga Oasis‚ Egypt. El-Bagawat necropolis is dating back to the 4th century AD.

and sampling techniques Spectrophotometer Spectrophotometry in chemistry is a quantitative measure of the reflection or transmission of material properties as a function of wavelength. It is more specialized than the term electromagnetic spectroscopy which is general in that spectrophotometry deals with near-ultraviolet‚ visible light‚ and near-infrared‚ but doesn’t cover the techniques of time-resolved spectroscopic . Spectrophotometer is used in Spectrophotometry. A spectrophotometer is

Mass Spectroscopy Mass spectroscopy is a method used in science and industry in order to obtain the masses and relative concentrations of atoms and molecules and to detect isotopes in a sample based on their masses. In order to do this the method requires an instrument called the ‘mass spectrometer’‚ of which‚ is able extract accurate information of the relative masses of isotopes and their relative abundance. This makes the mass spectrometer very useful for applications such as carbon dating

Abstract Soil reflectance spectroscopy is a well known technique to assess soil properties rapidly and quantitatively both in point (Spectroscopy) and image (Imaging Spectroscopy (IS)) domains. The quantitative approach has been developed in the past two decades by many researchers and many papers have been published on this subject in the scientific literature. Basically‚ the quantitative approach has been adopted from other disciplines (e.g. food‚ textile‚ pharmaceutical); whereas the mapping

Emission Spectroscopy The purpose of this lab was to see that when elements are heated‚ they may enter and excited state. We proved this by doing a flame test. During Part A‚ we used a spectroscope where all of the colors are arranged for you; whereas in Part B‚ we could see and make the colors ourselves and get a more accurate reading of the flames. We had specific elements we were told to put on the wire loop‚ and when we did that we saw different color flames come out of the Bunsen burner. That

Also‚ Fourier transform infrared spectroscopy (FT-IR) is widely used to confirm the product obtained after decolorization of dye degradation experiments [15]. It helps in determination of reaction

Vibration- Rotation Spectroscopy of HCl and DCl Purpose: To determine the fundamental vibration frequency and bond length for H35Cl‚ H37Cl‚ D35Cl‚ and D37Cl and to compare the isotope effects to theoretically predicted values. Introduction Vibration spectroscopy is one of the most important tools for the accurate determination of molecular structure. Vibration spectroscopy also plays an important role in environmental chemistry. For example‚ the albedo of the earth’s atmosphere is controlled by the
