    Absorption Spectroscopy Author: Lab Partners: Instructor: Chem 152 Date Work Performed: Date Work Submitted: Abstract A Beer’s Law analysis was used to determine the molar absorptivity of a Red-40 food dye. Using a spectrometer‚ the best wavelength to use for the analysis of this dye was determined to be 501nm. A series of dilutions were performed and the concentrations were calculated to find ‘E‚’ the molar absorptivity‚ which was determined to be 18035 M-1 cm-1. Introduction

    2.7 Raman spectroscopy Principle: Raman spectroscopy is based on the use of a laser light to induce oscillation and rotation in human fluids containing glucose. Because the emission of scattered light is influenced by molecular vibration‚ it is possible to estimate glucose concentration in human fluids [24]. This effect depends on the concentration of the glucose molecules. This technique can measure very weak signals‚ even in human fluids. The wavelength range of Raman spectrum is considered to

    Models of the Atom: a Historical Perspective John Dalton Early Greek Theories • 400 B.C. - Democritus thought matter could not be divided indefinitely. • This led to the idea of atoms in a void. fire Democritus • 1800 -Dalton proposed a modern atomic model based on experimentation not on pure reason. All matter is made of atoms. Atoms of an element are identical. Each element has different atoms. Atoms of different elements combine in constant ratios to form compounds. • Atoms are rearranged in
