Experimental and Computation Vibration-Rotation Spectroscopy for Carbon Monoxide Through the Use of High-Resolution Infrared (IR) Spectra Introduction: The goal of this experiment is to study the most precise way of measuring molecular bond lengths and introduction to computational software used for studying molecular properties. This is of interest in that the instrument to being used, a Fourier-transform infrared (FT-IR) spectrometer, can measure the vibrational and rotational transitions
that there are a high range of reactant in the product because the melting point for Ferrocene is 172 and for Acetylferrocene is about 81-83. It is also showed that the product is not pure, and also the TLC was run. Table of wavenumbers and Functional Groups Wavenumbers Functional
The NH bond stretching at wavenumber 3325.81 cm-1 and 3325.44 cm-1 in USP grade acetaminophen and synthesised acetaminophen. The bending of NH bond formed a band around 1610 cm-1. The presence of carbonyl group in both synthesised and USP grade acetaminophen gave a peak at wavenumber 1663.50 cm-1 and 1664.71 cm-1. Acetaminophen is para-disubstitution, it formed a peak around wavenumber 837cm-1. There were two small broad peaks found in both spectrum around wavenumber 3160 cm-1 to 3210 cm-1, this
have been my product because of the results of my IR. I had a broad large absorption is the range of 3200 to 3500 wavenumbers. This indicates the presence of an alcohol. If my compound had been fully oxidized then there would be no such alcohol present. Also, because of my IR, I know that my compound was one of the other 2 compounds because of the strong sharp absorption at 1705 wavenumbers. This indicates the presence of a carbonyl. Also, my 2,4-DNP test was positive. Therefore I had to prove which
For the Identification of a Volatile Liquid Data Analysis I had the unknown number A53826. There are many ways that I used to determine the identification of the liquid. Some characteristics of the liquid that will help further in my research are that the liquid was colorless with a harsh strong odor. Before I did my research there were many components I did to help with my research. I first started by performing an experiment that helped determine the mass of my sample. The mass of my sample is
within the compound. As well, stronger bonds in the substance and light atoms will vibrate or rotate at a higher frequency, thus acquiring a higher wavenumber. A wavenumber is the number of wave cycles in one centimetre. The information gathered from the IR spectroscopy can be interpreted from an IR spectrum graph of the material. On such a graph, the wavenumber is on the x-axis, whereas the transmittance percentage is on the y-axis. The transmittance percentage indicates the strength of the light that
expressed that the alkenes within the final product were produced at a ratio of 8.7:1 or 9 molecules of 1-methylcyclohexene to every 1 molecule of 3-methylcyclohexene. Additionally, the IR spectroscopy test yielded spikes that aligned with the desired wavenumber for alkene components. The graph also did not have spikes within the OH bond region as the starting material graph did, which indicates that OH was not in the final product and the purification of the sample went

Conclusions A short range force constant model has been applied involving several stretching and bending force constants to evaluate the Raman and infrared wavenumbers of inorganic complex structured compounds Cs2HgCl4, Cs2CdBr4
is the main component that helps us form the benzene structure to form our molecule. This zone is typically around 1680-1450cm-1 wavenumbers. Lastly, the last box as seen in the diagram above in the orange box represents another functional group. The functional group that zone 4 represents is a C-Cl bond. This singe carbon and chlorine bond is located on the wavenumber axis of 600-800cm-1 and in addition its intensity is high. In conclusion from the graph observed, we managed to determine the main
In this experiment the purpose was to synthesize a synthetic dye, methyl orange, and test its effectiveness by performing a dye test with fabric. Methyl orange is an azo dye made from a synthesis reaction between sulfanilic acid and N,N-dimethylaniline. The preparation for this synthesis involves two steps: diazotization and coupling reaction. The diazotization step is the first step where the sulfanilic acid sodium salt reacts with the sodium nitrite in HCl to form an unstable diazonium salt. The
The frequency is expressed in wavenumbers (cm-1). There are peaks that point downward. A peak corresponds to the frequency of vibration of one particular functional group present in the molecule. Thus, a peak in the spectrum implies a functional group and the number of peaks can imply how

The C-H stretch is at 2976.58 cm-1 and the N-H stretch is at 3265.02 cm-1. These peaks all correspond well with the literature values2. Conclusion Product 3 was isolated in a low yield of 27% and with

precise basis than 6-311+G. These values are not satisfactory for this molecule in comparison to expected values, but that does not mean Spartan will fail for all molecules, but at the very least, it seems to be inadequate for phosgene. The very low wavenumber region of the spectrum (sometimes called the "fingerprint region") is the most inaccurate area, but with good reason. This region usually corresponds to the more complex molecular oscillations, so it is not surprising that Spartan had more trouble
Abstarct: In this paper we get an overview of the dielectric resonator antenna which replaced the simple form of antennas that were being used for the past ten years. These dielectric antenna have been of a great importance to the research work in antenna field as these have a great dielectric constant and higher Q factor than the other isotropic or directive antennas. Earlier these antennas were considered to be energy storage devices but in this paper we have made use of the DRA antennas as radiators
Abstract In this work, the mechanical and barrier properties were examined for Polypropylene (PP) film in which the surface of the film was modified by Oxygen plasma treatment. The PP film was treated in various intervals of time of 60 s, 120 s, 180 s, 240 s and 300 s with three various RF power settings of 7.2 W, 10.2 W, 29.6 W. The contact angle was measured to characterize the wettability. The oxygen functional groups were generated on the surface of oxygen modified PP which was observed by Fourier
Nonuniversal Effects in Bose-Einstein Condensation In 1924 Albert Einstein predicted the existence of a special type of matter now known as Bose-Einstein condensation. However, it was not until 1995 that simple BEC (Bose-Einstein condensation) was observed in a low-density Bosonic gas. This recent experimental breakthrough has led to renewed theoretical interest in BEC. The focus of my research is to more accurately determine basic properties of homogeneous Bose gases. In particular nonuniversal
