Rote memorization, with flashcards possibly, is the only way I can think of. Like the other poster said, look for carbonyls, alcohols, alkenes, and amino peaks (a weak, wide peak at about ... 3200 or so)

It's fairly easy don't worry.\n\nNo need for d level splitting diagrams to answer this since we're dealing with N and F:  use the spectrochemical series to make an assumption about the ligand.  The difference in t2g and eg levels (∆o) determines whether a complex is low or high spin.  If both ligands were the same, we would have to look at the oxidation state of the ligand in the complex.\n\nHalides <  Oxygen ligands  <  Nitrogen ligands < CN- ligands\n\n   ALWAYS HIGH SPIN    ---------------            ALWAYS LOW SPIN\n\nIf ∆o > P, then a complex is low spin.  IF ∆o < P the complex is high spin.

If you are doing an IR Spectrum on the alkene that has ALREADY been brominated, the ~1600-1675 cm-1 peak for an alkene is not there any more.  Once brominated, the C-X bond will resonate at below 600 cm-1 but it is in the fingerprint region and is not very strong and distinguishable.  So all that is left is, yes, the sp3 bond fo C-H.

Disregard the previous gibberish.\nTo estimate purity you need to be able to interpret the spectrum to determine which peaks belong to your product.  Assuming that you can do this, the entire spectrum needs to be integrated and from the integrals of the individual peaks you can determine the ratio of impurities present and thereby estimate the purity of your product.

What can we do, though? You need to take a relatively pure sample of your compound and dissolve it in a deuterated solvent (say CDCl3). Then you can use an NMR to find the different peaks.

Most plastics are made of organic compounds.  The inter-atomic bonds of organic chemicals have quantum energies that correspond precisely with the energy levels in the infrared region of the electromagnetic spectrum.  \n\nIf you irradiate an organic chemical with IR, it will absorb quanta of IR energy that correspond to specific vibrational energies in the molecule -- this excites the bond and makes it vibrate more rapidly and with greater amplitude.  By scanning across the entire range of IR frequencies, you get a "fingerprint" of absorptions that can help to identify the nature of the organic chemical being scanned.\n\nThat's it in a nutshell -- I hope it helps.  There are lots of instrumental analysis books available that will explain it in more detail.

IR analysis of substances is very easy. You just put a few milligrams of the (solid, liquid, or gas) sample onto the IR cell, scan with IR and you get the output spectra. You use a guide to interpret the spectra. These are available in chemistry books and in the net. With paint, it depends on which component of paint you wish to analyze. Normally each component - pigment, additives, binders, etc - has its own characteristic chemical, and hence functional groups to look out for. If you don't need the solvent, then evaporate it off and analyze the sample you obtained. You can also do some preliminary separation by chromatography, centrifugation, filtration, etc. Paints indeed give color to life!
