The rotation of a diatomic molecule such as 'H1271 can be modeled as a light particle ('H) rotating around a heavier, almost-stationary mas: 1271 at a distance of 160 pm. Suppose the same molecule rotates in 3D space, such that the TH atom can be treated as a particle on a sphere ass with radius 160 pm. Use the effective mass to estimate the wavelength of radiation emitted when the molecule falls from its first rotational excited state to its ground state. 753 иm 23 µm 130 μm 561 um
