Again, we're just going over infrared spectroscopy, so recall we have our definition at the top.
00:07
And what we will be doing here is looking at absorptions that we might expect in these molecules, given in our examples.
00:14
So in our first structure, we have a c .h .o.
00:17
This is an aldehyde.
00:19
And if it is saturated, then we would see a absorption of 1725.
00:27
If it's conjugated, 16, 90, and if it's conjugated, 16, 90, and if it's a saturated, and if it's saturated, it's aromatic about 1 ,700, all in wave numbers.
00:34
So they're all in very close proximity.
00:37
Secondly, we're looking at an no2 group...
