Duplicate of Is all angular momentum quantized? | |
| Nov 18, 2015 at 19:44 | comment | added | Bill N | He didn't do any exact calculations. He made an educated guess about whether $L$ would be quantized and how. I'm not aware of any contemporaneous notes which Bohr made about why he made that particular guess. He may have made several before he found a form which gave the proper wavelengths for the emission spectra. @RobinEkman I think we teach it because it shows how scientists attack a "frontier" problem, and end up with a partially right, yet wrong answer. | |

| Nov 18, 2015 at 15:39 | comment | added | ACuriousMind♦ | @Praan: "Assuming, with Bohr, that quantized values of L are equally spaced[...]" You may be able to derive that it is quantized from slightly different assumptions, but that formula is basically put in by hand. | |
| Nov 18, 2015 at 15:36 | comment | added | Praan | @ACuriousMind No it's not. It follows from the assumptions. See en.wikipedia.org/wiki/Correspondence_principle#Bohr_model | |
| Nov 18, 2015 at 15:33 | comment | added | ACuriousMind♦ | That's an assumption of the Bohr model. You can't derive it. For why angular momentum is quantized in the true quantum theory, see e.g. this question. | |
