in short. the spin-orbit interaction causes splitting of 2P energy level into two. 2P(3/2) and 2P(1/2) which are very close in value.. *Fine structure*

Since the electron does not spin, what is going on at the atomic level? Electron spin is just how we describe this property since a macroscopic object with charge that is spinning does this in a magnetic field. However, the electron is not actually spinning although it does have a small magnetic field.

Very interesting ! One thing I didn’t understand : why aren’t there also 2 states for the 1s orbital ? And also, isn’t there a 2s orbital in between offering more energy lines ?
@KENACT13 жыл бұрын
Some things that are unclear. Is there an equal probability that the electron will be plus 1 or minus 1 in spin, leading to an equal probability of either spectral line, or is one line more common than the other? When an electron jumps to a lower orbital, does it give off one line or both? The reasoning behind that question is that if multiple jumps lead to the dual lines, that means the lines, if animated at insanely high speed, would appear to flicker. Also, if one electron jump leads to both lines, would that mean two photons of different energy released from one electron in one jump? Here your examining the hydrogen atom, but with heavier elements, if there is an odd number of electrons in the shell, would the lines of different frequency be unequal?

Can you please explain to me what will happen if this state is placed into an external magnetic field? From what I understand, the 2P(3/2) state will again split into -3/2, -1/2, 1/2 and 3/2. Same thing will happen to the 2P(1/2) state. It will split into -1/2 and 1/2. Is this correct?

Anyone got the answer to this yet? Been wondering exactly the same
@SmokeyBCN5 жыл бұрын
@@nikosiwannoy5669 the answer is yes. The Zeeman effect will produce six lines from the transition between 2P to 1S, which is why the Zeeman effect should not be discussed witout the consideration of fine structure, because it is misleading.
@Goldslate73Ай бұрын
So where exactly is the electron? (I mean, it's in the p subshell, alright. But when it transitions to give the two spectra lines, is it transitioning from the P1/2 and P3/2 states at the same time?)
@amandhindsa22957 жыл бұрын
if there is a single electon it can either spin up or down either +half or -half i.e electron will revolve clockwise or anticlock wise but then how can a single electron can have two spin +half and -half at a single time interval how can we consider two spin's? PLEASE ANSWER MY QUE.

liked these videos.. but one question is that what if proton(as we assumed orbiting the electron) is moving with some constant speed, maybe it will create constant magnetic field, so won't the spin angular dipole moment aligned at one moment? then how will it keep rotating?
@puneetacademy80734 жыл бұрын
because not only 1 electron and 1 proton are there. what about spin angular dipole moment of other electrons ..here we have sample of hydrogen which is made up of large number of atoms.this means large no of electrons are present there. the electron revolving around a nucleus of one atom must have some influence of nearby electron ( revolving around other nucleus).

If you have only one electron why do you have two emission lines? You didnt explain how you have two emission lines with only one electron. That connection of how this is possible is not clear
@Rudolphhhhhh5 жыл бұрын
Because inside the "sample" of Hydrogen, there is statistically (approximately) one half of atoms whose electron has a spin +1/2 and one half of atoms whose electron has a spin -1/2. That is why we have two emission lines.
