Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.The transitions occur between 5 energy levels, from ##n=0## to ##n=4##. I only included transitions between neighbouring energy levels...

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.So I said, in words, "The red line shows a dip in the intensity of detected radiation. This means that the sample of CO has absorbed...

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.Are we interested in: $$\Delta \nu = \frac{\hbar^2}{I}?$$

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.##\hbar## is the same as you. Mass of carbon ##2 \times 10^{-26}## and mass of oxygen ##2.656 \times 10^{-26}## To make the dimensions...

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.Look at post #9. my expression for ##a## is correct

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.I get ##2.8 \times 10^{-10} \text{m}##

Like.
It's incomplete. You didn't do what the last sentence in part (d) is asking you to do. You need to come up with a number. That's the... -
Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.I don't understand. What is wrong with my post #29? $$ a = \sqrt{\frac{\hbar}{4} \frac{m_1+m_2}{m_1m_2}}$$
-
Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.Okay I just looked at the question again. The distance between the dips looks pretty constant. So we just say: $$\Delta \nu = \nu_j -...

Hhmparticle9 posted the thread Need a book on Modern Physics to supplement Griffiths QM in Science and Math Textbooks.I am reading Introduction to Quantum Mechanics by Griffiths. The mathematics and most the physics are going down well, but now and again...

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.Okay. Is this another 20th century physics thing? Okay. So to finish part c): $$E_{\gamma} = 2 \pi \hbar \nu \text{ and } E_{n+1} - E_n...

Hhmparticle9 replied to the thread Griffiths' Quantum Mechanics Problem 4.27 : Diatomic particles.What I meant when I said $$2E_{\gamma} = E_{n+2} - E_n$$ is that two photons are emitted, not one photon with twice the energy.
