Fourier transform spectroscopy

In Metamorphosis by Franz Kafka, Gregor is not the only one who transforms but the whole family dynamic transforms due to his metamorphosis into a cockroach. Due to that transformation, there is conflict between family members particularly between Gregor’s mother and Grete, his sister. This transformation helps the readers see another view on human nature and family dynamics. From the start of the story, Gregor is transformed into a cockroach, which leads his family into conflict about how to…

No matter where a person may come from, everyone encounters a similar journey. The journey that is heard in stories is symbolic to what anyone may go through in life. In the story “A worn path”, an old women goes through many obstacles as she is on the pathway to acquiring what she sought after. In order to better convey the hero’s journey in the story A Worn Path, Eudora Welty uses characterization, symbolism, and conflict. In the story characterization is used to describe the main character…

Each spot had its Rf value recorded. A 10 ml graduated cylinder was filled with hexane. Then, two microliters of the carvone-hexane solution were added to the hexane using a micro pipette. This solution was moved into the crystal container for UV spectroscopy. The UV spectra was taken from 200 to 400 nm and the concentration of the sample was 2.0E-4. The absorbance was recorded at 232 nm and 273 nm. Results The carvone product was weighed to be 1.88 g and appeared to be a mostly clear liquid.…

Adhikary, Sujit. “Vermicompost, the story of organic gold: A review.” Scientific Research, Vol. 3, No. 7. Scientific Research Publishing Inc., [circa 2014], cesantaclara.ucanr.edu/files/235723. In the online article, “Vermicompost, the story of organic gold: A review,” the author dives into the benefits of vermicomposting by explaining the basics of the concept, and then digs deeper into the values and assets of this “organic gold.” The article states how vermicomposting not only gets rid of…

Spectrophotometry is a method in which organic and inorganic substances are identified or characterized by the use of electromagnetic radiation. Electromagnetic radiation not only includes light (or photons), but thermal energy as well. While the electromagnetic spectrum consists of wavelengths between gamma radiation and the Far IR, most spectrophotometric methods rely on the UV and visible region. In order to use spectrophotometric methods, the sample being analyzed must be able to absorb the…

Figure 1 shows the relationship between concentration and absorbance known as the Beer-Lambert law or calibration curve. The data from the made solutions in table 2 was used to create the graph. The graph has a linear trend line that predicts where a point would fall on the graph. The equation of the trend line is equation 7: y=0.9508x-0.0055 with a R2 value of 0.99943. This equation was used to find the true concentration of the made solutions as well as the unknown solution. The R2 value…

Hey Mom, I know you’re dying to know how my semester is going so I thought I’d share with you some of the assignments I’ve been working on. I just finished my first chemistry lab project involving drugs! Yes, drugs, but not the ones you’re thinking about. We worked with Sulfanilamide, Phenacetin, Acetaminophen, and your favorite, Caffeine. The goal for the experiment was to determine where the drugs may reside according to their properties. We learned that there are parts in the cell that are…

1 WRITTEN ESSAY Paragraph 1 The FePO4 crystal is examined at various temperatures ranging between 294K and 1073K by neutron powder diffraction. At relatively low temperatures, FePO4 adopts an α-quartz structure, which is tetrahedral. High pressures causes a phase change to a more dense octahedral structure, which is known as β-phase. The transition temperature is 980K. Cutoffs can be observed during the firstorder transition,. For α-phase, the increases in cell parameters…

Discussion/Scientific Explanation: In order to successfully analyze colas, one must become familiar with a Spectrophotometer 20. In order to do this, one must figure out determine the relationship between the wavelength of light absorbed and the color of a compound. Next, one must determine a way to relate the amount of light absorbed with the concentration of the solution. After gaining knowledge about these two parts of the lab, one will be able to determine how a Spectrophotometer 20 can be…

Introduction: The goal of this lab was for students to learn how to use a spectrophotometer to find the absorbance of four known copper (II) sulfate solutions, four copper (II) sulfate solutions that were created by dilution, and one unknown copper (II) sulfate solution. The purpose of this experiment was to help students learn how to use the Spec-20, which is a machine that measures the transmittance and absorbance of a solution, learn about the linear relationship between absorbance and…
