Okay, so here we have a mass spec of chlorine, and chlorine we're assuming, we're taking it's a chlorine gas.
00:06
There's two chlorines.
00:08
All right.
00:09
And so we have three peaks from this mass spec.
00:16
So if we have a mass spec, this axis would be intensity.
00:24
And then we have our mzs, one out 70, 72, 74.
00:33
This is going to be tossed.
00:34
This is a little shorter and this signal is shorter.
00:39
So here's our mass spec of chlorine gas.
00:42
We want to know which of these isotopes are making up the different peaks.
00:48
So this is mass charge.
00:49
We're assuming that the charge for each one is going to be one in this case, in this range.
00:54
And so this is a direct measure, basically, of the mass of each of these chlorines, chlorine molecules.
01:01
All right.
01:02
And so there are two isotopes is chlorine 35, which has a mass of 35, and chlorine 37, which has a mass of 37.
01:10
And 35 is about three times more abundant than our 37 mass.
01:16
So what are making up these three peaks? so if we're looking at the mz peak of 70, that's going to be two chlorine 35s...
