How can i determine if i have and ortho, para, or meta isomer if im looking at an IR spectrum??

Compare your spectrum to the data in the reference.  o,m,p are listed towards the end of the table.

I entered that into the Sigma site and it suggested that maybe I meant muramic acid.  And you can find an FT-IR spectrum on their site.  I really just suggest going to various chemical supply websites and looking at their information.  There are as many spectra as their are ways of testing for the presence of that acid.

Key points to look for include:\n\nInfrared\n-NO2 bonds: 1515-1560, 1345-1385\nAlkenes: C-H: 3020-3080 (moderate), 675-1000\n         C=C: 1640-1680(variable) \nIf wet: Large OH hump in the 3500 area... should obliterate most other peaks in the area.\n\nI am not as up to scratch with NMR.\n\nThis is a common compound and an IR and NMR spectra should be easily found on the internet. I recommend chaecking them carefully as jus tlooking for the peaks above will probably not be highly useful.\n\nEven better than the internet is a resource book, any laboratory or university library should have such resource books.\n\nPersonally I recommend that if you are doing much organic chemistry to get 'Organic CHemistry' by Morrison R.T. and Boyd R.N., published by Prentice Hall.\nThis book has an excellent guide for spectra.

Colorimetry is a specrophotometric determination but as the name suggests it revolves around the forming colour so the visible part of the EM spectrum. It is usually made using simple instruments usually visual comparison to standards or simple filter spectrophotomers. The vavelength discrimination is thes machines is somewhat poor and deviations from Beer's law (abs proportional to cocnc) can occur. Despite this, these techniques are widely used very successfully in routine chemical analysis.\n\nSpectrophotometry is available across most of the EM spectrum form gamma rays to IR. The better instruments have much better sources and monochromators to produce "single" wavelength radiation. Generally the detection equipment is superior as well. Also being a spectrophotomer the source, monochromator sample and detector is "in line". You might also want to check fluometry is you want to go further.

Infrared is light that has a wavelength outside the bottom of the visible spectrum--it is essentially the "colour" that occurs before red (the lowest visible wavelength).\n\nThe invisible "light" that occurs at the top of the visible spectrum is ultraviolet.\n\nBoth of them can't be seen with the naked eye, but can alter the way the eyes perceive the other--visible--colours.

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)

Yes.  Or at least it can by using deep level optical spectroscopy (DLOS).  See the reference below:

first one: no, your missing an Mn on the right.\nSecond one: yes\nthird one: no, you're missing 5 ammonia on the left\n\nthe rest as standard metathesis reactions, use the ones u've done as a guide

That simplifies to 3[2x-1]>12\n\n[2x-1]>4\n\n2x-1>4    2x-1<-4\n\nx>5/2  or x<-3/2\n\nWhen you have absolute values, you have to look at both ends of the spectrum

I don't know that question.\n\nI can tell you that it's an octahedral complex. The two isomers would be CIS (Both chlorides adjacent to each other) and TRANS (both chlorines opposite each other)

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!

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.

did you also prepare a standard solution? because the way i do it, is that i have a standard so i can compare the 2 absorbtions (same wavelength)...You know the equation..

By using spectra. Each element has characteristic frequencies of light that it emits or absorbs. If light from the star is spread out into a spectrum (like a rainbow), there will be dark lines for absorbtion and bright lines for emission. By identifying the chemicals that correspond to those lines, we deduce the composition of the star.
