.t 5. Calculate the frequency of the emitted photon for the rotational J-l --,-0 transition for I...
Calculate the frequency of the J = 10 ← 9 transition in the pure rotational spectrum of 12C16O. Assume the equilibrium bond length is 109.99pm. What is the Frequency in Hz? What is the corresponding wavenumber in cm-1?
Suppose that the wavenumber of the J = 1 ← 0 rotational transition of 1H79Br considered as a rigid rotor was measured to be 17.89 cm-1, what is (a) the moment of inertia of the molecule? Ans = _____ kg-m2 (b) the bond length? Ans = _____ Angstroms (Given the isotopic masses:(m(79Br) = 78.9183 amu, m(81Br) = 80.9163 amu)
(4) Thermodynamic data suggests that copper monohalides (CuX) should exist as polymers in the gas phaso However, scientists have successfully synthesized CuX monomers and characterized them using microwave spectroscopy For Cu Br the J-13 14,J-1415 and J-1516 transitions occurred at 84421.34 MHz, 90449.25 MHz and 96476.72 MHz, respectively. Assuming Cu Br behaves as a 3D rigid rotor, answer the following questions. Note: Absorption frequency (in units of Hz) of a rotational transition (aka peak position in a microwave spectrum) corresponding...
