🧵 Can a molecule absorb two photons at the same time?
Anonymous at Thu, 17 Oct 2024 02:54:21 UTC No. 16435651
The Stark-Einstein principle confuses me.
Suppose that an H2 molecule (with one stretching degree of liberty) is excited by a photon in the infrarred range of the spectrum, making the H-H bond stretch. At the same time, it is excited by a photon in the microwave range of the spectrum, making it rotate.
Is this possible?
Same goes to the hydrogen atom. Suppose that it is excited by one photon with enough energy to take the electron to orbital 2s and another photon so energetic that the electron reaches an unbound state and is taken to infinite. What happens them?
Is there some form of weird coupling if two photons were to try and excite a molecule at the same time?

i'm getting exhausted OP
apparently true
time to take a break
it's
i'll see at wiki
been good evening.

Yes, a molecule or an atom with multiple electrons can absorb or emit multiple electrons (or both) at the same time.

The electron quantum jump is synonymous with the photon exchange, so one electron can't normally do what you're describing. It is possible, however, for an electron to release or absorb two photons in very rapid sequence such that, from a macroscopic perspective, it is nearly simultaneous.

*I meant "multiple photons" on that first answer.

This is all complete bullshit of course. QM is entirely incapable of modelling the path of a single photon, much less the absorption and re-emittance of one by a molecule or atom.

No, there is only one photon.

yes. it's called degeneracy. really.

I am not very smart, but I am pretty surr the whole of spectroscopy is founded on aborption and emittance of electrons.
Sorry, guys. I am still very confused. Anyone else can chime in?

From whose perspective?

Outside observer. You caught me.
Thinking about my question, I am beginning to think it is impossible for two photons to hit a molecule at the same time. Position and time operators should commute if they refer to two different particles, no? Sorry, my IQ is barely 105, I got into this watching big bang theory, now I am very confused.

Short answer, "yes" with an "if." Long answer, "no" with a "but."

I would sha it can integrate them would make more sense, and why not! I immagine yes.
I don't know which one, I could figure it out probubly if I thought harder.

t. I don't know anything about QM but I do love dogma so I will assume you are wrong.

You can try it yourself at home with a microwave. A pair of grapes acts as a nice 2.4 GHz resonator. It takes ~31.63 eV to eject an electron from a potassium ion, while a single microwave photon is measly ~0.00000993 eV.

Where does the photon come from?
Where is the photon when the electron is excited?
Imagine you have a bowl with an apple in it, the apple is an electron, the bowl is an atom I geuss, an incoming grape is a photon, the photon wedges under the apple, the apple is now in a higher energy state, the apple loses its balence, it gets tired, it falls off the grape, causing the grape to be emitted out of the bowl.
Or it's more like the the apple is made of metal, the grape is made of metal, the grape hits the apple and makes the apple spin around the bowl, eventually the apple swirls back down and knocks the grape out.
Oh the grape is also a longish piece of metal that is wiggling up and down.
