Document Summary
Video 1 intro, uv/vis, and ir intro. This provides information about the electronic structure of the molecule. Not much structural information comes from this, so it is used very little: infrared (ir) spec. Provides information about the types of bonds in a molecule based on bond strength and masses attached to each end of the bonds. Will go over where common functional groups absorb in the ir spectrum: mass spec (ms) 12. 6, 19. 3e and 26. 8a in loudon are important to look at: nuclear magnetic resonance nmr spec. Can get very detailed and precise information of the structure of a lot of molecules. Electromagnetic radiation review: e = hv = hc/(lamda) H = 6. 625 x 10^-34 j s. Uv/vis absorption spectroscopy: especially useful for conjugated pi systems, as one of the most common conjugated forms of a pi system is from pi to pi* Typically, the jump from the homo (highest-energy occupied molecular.
