Okay. So those questions asking if we can look at the differences in detection methods for a pretty simple physical property being bond length and see if we can explain why different detection methods might give us different answers. And this is a very important question. The more detection methods and more properties you need to look into. So it uses the example B to H seven, an ion. And we're not gonna worry about Louis structure for this because it doesn't matter and it's kind of a nightmare. So let's go ahead and just look at the fact that we have a boron hydrogen bond on a terminal end. And so if we look at X ray scattering, we get a A bond length of about 103 Pekka meters. And if we look at neutron scattering, we get a length of 118 Pekka meters Pekka meters. Okay, so both of these are incredibly accurate methods of measuring bond length, Um, to the point that X ray diffraction is used as the way that we know how whole proteins look. Onda many other molecules and neutron scattering is probably more accurate, but it's very expensive. So we need to know. We can't say that one of them is just fundamentally less certain than the other. They're both very, very good, uh, methods of detection. So we need to examine why, for this example, we see a different length for this bond. So let's go ahead and look at that. If we have an Adam, here's the nucleus. Here's the core electrons, and we're gonna say there's another one here. Here's its core electrons and they're bound with their valence electrons, right? So, nuclei, I'll do this for nucleus for a neutron are going to come in and be deflected by the nuclei, right? And so, using this angle and this distance, which is not drawn proportionately. But this is going to be the same distance is this, and using this this'll angle is going to be the same. Using the difference in distance and angles and everything of different atoms, we can get the whole shape. It's very, very accurate and very, very good. And so nuclear I will bounce off of the, uh, new neutrons will bounce off of the nuclei, but if they passed through the electron field, they'll basically just go right through because they're not charged or anything. So if we do the same thing with, um X rays do this for X ray. Right? So they're going to come in and bounce off of the core electrons. Okay, Because while x rays are here, so this is nuclear notation and X rays are also zero. They're 00 gamma like that, and they have an Elektronik wave and a magnetic wave being radiation. So some of them will also go through the magnet, the electron, the electrons in the bonding area. But some of them will also be deflected, right? And so not very many will actually be deflected for this. But some of them will. Some of them will also be deflected from the nuclei. So we have these different ways that they're deflected. And remember the new the neutrons will Onley be deflected by the nuclear. That's part of what makes it so expensive. Because nuclear neutrons are much, much harder to control and simple radiation. Oscar ahead and redraw. This didn't want that to happen. Sorry. So Okay, so let's go ahead and look at why. That leads to a difference. Mhm. If we don't have core electrons like in hydrogen. Here's a Djetou. Then the Onley things that the electron that the X rays Kenbrell ounce off of are going to be the nuclei and the meat the mean electron field. Right. So that leads to this uncertainty when you don't have core electrons. And actually, the accuracy of X ray diffraction is going to be proportional to the the nuclear charge of so the nuclei, their place on the periodic table. So hydrogen having one is going to lead to the least accurate X ray diffraction. Um, possible. Really? You can't really have an X ray diffraction worse than for H two. And if we look at what boron Boron has a z of on Lee five, which is really not that much better. But it does have the one s and two s core electrons. So at least that Boren has that going for it. But you really can't do um, X ray diffraction for hydrogen very easily. So that's where this difference comes from in these two. It's just that hydrogen is incredibly difficult to utilize the x ray diffraction method for Okay, so that's really it. Thank you.
