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

Individual Discussion Spectroscopy Dry Lab Lab Section M5 - Group 6 January 24‚ 2015 Discussion In this laboratory assignment‚ the spectroscopy data and molecular formula were given for 3 unknowns. An effort was made to conclusively identify these unknown samples using only the spectroscopy data‚ specifically 1H-NMR‚ 13C-NMR‚ and IR spectroscopy. Although mass spectrometry was given for the samples as well‚ its use was suggested only for confirmation‚ not identification‚ of the unknowns

Lab #4 Emission Spectroscopy and Flame Test Date of Lab: 10/24/13 OBJECTIVE To observe a continuous spectrum‚ emission spectrum‚ and an absorption spectrum‚ and be able to distinguish among the three. To be able to identify metal ions by doing a flame test and looking at a spectrum. At the same time increasing the ability to use and understanding of lab equipment‚ in this case‚ a spectroscope. To be able to calculate the frequency and energy of certain frequencies of light. PROCEDURE

Experiment H: Identification of an Unknown Organic Compound The objective of this lab was straightforward. We were given an unknown compound and we were to perform an IR spectroscopy and as well as NMR spectroscopy. With the IR spectroscopy‚ I was able to name the functional groups I have on my compound and further confirmed my assumptions by looking at the NMR spectroscopy after. The unknown number I was given was number 203. The molecular weight of the compound was 121. From the molecular weight

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
