Degree of freedom in diatomic molecule
WebDec 17, 2024 · If I have a diatomic molecule, so a linear molecule, $3N-5=6-5=1$ holds, since this vibrational degree of freedom corresponds to the stretching coordinate beetwen the two nuclei. If I consider water for example, I have a nonlinear triatomic molecule, so the formula says $3N-6=9-6=3$ vibrational degrees of freedom. Also in this case it makes … WebOct 11, 2015 · But it is easily seen that the rotation around the bond does not produce any motion at all. And that is why the diatomic molecule has only two degrees of freedom of rotation. Hope it is clear ...

WebApr 9, 2024 · There are three degrees of freedom in the case of the monoatomic gas. Thus, the average kinetic energy per degree of freedom is represented as- KEx= 1 2 KbT A molecule possesses three translational degrees of freedom, which is free to move in space and hence needs three coordinates in order to specify its location. WebJul 23, 2024 · But for a spring, which corresponds to 1 (dynamic) degree of freedom there are two (thermal) degrees of freedom from two quadratic terms ${1 \over 2 } \mu \dot \xi^2+{1\over 2} k \xi^2$. Same story for …
WebSo now it's time to do three or more atoms. So, let's take a look at polyatomic molecules. And in addition to the usual translational and electronic degrees of freedom, a polyatomic molecule can also rotate, as a diatomic can. But it also has multiple vibrations that distinguishes it from a diatomic which has a single vibration.
