Hillary won today we're doing Chapter fourteen Problem, too. And this question states that we have in Proton and more spectrum for the small cube here. One, two meth Oxy, I think. And we record the NMR spectrum using a three hundred make it hurts magnet on you Get to signals. One signal from molecule is one thousand and seventeen hertz and the other signal is at eighteen. Thirty. No, sir. It is at ten. Sixty five hurts downstream from your reference TMS point zero. So Partick asked you to complete the chemical shift for each absorption value and part B asked you what frequency with each absorption occurred at the spectrum are recorded on the five hundred megahertz Magnus. So if you were called the equation to determine your chemical shift so your chemical shift or Delta sign equals your observed chemical chef value and this is an occurrence. This is divided by the operating frequency theater and mar and make her so the magnet strength of your anymore. Sophie Plunkett, This equation using information have provided so for part a pacifying the chemical shift value. So we know that for this signal here, the ten seventeen signoff our chemical shit it pulls are observed chemical shit. That ten seventeen purse divided by the operating frequency of Imagine it fifteen hundred megahertz. This closes chemical shift value of three point three nine p. P. M. And then for the second value, your chemical shit you calls ten sixty five hurts on DH. That's also in the three hundred player hurts magnets, and that gives us a chemical shift value of three point five five parts per million. But now what happens if your magnet strip even increases? Well, the whole beauty of this chemical shift is that for girls on the strength of your magnet, your chemical shift will stay the same. The racial between your observed shift and your freedom to your magnet vibration will always be the constant. So if you have ah, stronger magnets, then you need higher energy to cause that spend flip toe happen, so the ratio will never change. But these these arbitrary values will change. But that's why we use the chemical shift value because it's unanimous the girls of respect of a magnet. So for B now we're trying to find so being asked us, what happens if we use the five hundred million years a magnet. So we know that for eight to ten seventeen, signaling ate this part. Here we had a similar shift value, three point three nine parts per million. So what's our new observed chemical shift? If we use a five hundred major magnets on, well, hurts value, it will be sixteen ninety five. And if I use the same equation for the bottom value I've known as a parts reason five hundred megahertz magnets, no new observed value is seventeen, certainly far, so five.
