So here again we're just looking at infrared spectroscopy and we're going to be discussing how we may be able to utilize this tool in chemistry in order to distinguish between pairs of molecules that we have present.
00:11
So i've got all of my examples along the side.
00:15
We have a all the way through h here, i believe.
00:20
And so i'll just run through a few of these with you.
00:23
So the ether has two peaks around 1 ,200 which represents each of the co bonds in the structure.
00:30
Whereas the other molecule will lack these bands.
00:33
In the second example, the oh functional group is very broad and above 3 ,000 centimeters to the minus 1, which is our wave number unit, whereas the other molecule will not have this present.
00:44
Our third example, c, the ether has two peaks around 1 ,200 and 1 ,050.
00:50
This represents each co bond of the structure.
00:54
The other molecule instead will have an nh band at 3 ,300 to 3 ,500...
