  This is being updated. For now, most of the material is from the Fall of 2002. Most material will remain the same (minor modifications) for 2003, but there will be changes. I hope to have this site updated by September 1, 2003

Experimental Topics, Chemistry 408

• Infrared Spectroscopy of Small Molecules (vibrational spectra with rotational details resolved.)
  • mid-IR of Diatomics (HBr, HCl, CO, DCl)
  • near-IR and first overtone (HBr)
  • mid IR of small polyatomics (SO₂, CO₂, H₂O, H₂CO, CH₄, C₂H₂)
  • IR to examine normal mode vibrations (C₆H₅-CH₃, CH₃OH)
• Visible Spectrum of I₂ Vapor
  high resolution electronic spectra; vibrational details resolved
• Polyacetylene
  • Synthesis, spectra and electronic proteries of a conjugated polymer
• HPLC (now that we have a new column that performs properly)
  • simple approach: aspirin, caffeine, acetaminophen in pain killers
  • perhaps more interesting: find the "hot" part of hot peppers; quantify
  • complex analytical sample: find atrazine (herbicide) in soil at the 1 part per million level or less
    • will need to use a method to concentrate the atraizine and to save the column from other impurities
    • SPE or Solid Phase Extraction technique
• GC (capillary column, flame ionization, internal standards)
• electrochemistry
• NMR
• Lasers and Time Resolved Fluorescence
  • Laser (Nitrogen pulsed, tunable dye laser)
  • Time resolved fluorescecne ( Ru(bpy)₃²⁺ )
  • Fluorescence quenching
  • Exiplex of pyrene
• Computers and Interfacing (Lab View software)
• Molecular Computations (Spartan Software)
