3. The spacing between the J = 0 and J = 1 lines (corresponding to l = 0,1 = 1 quantum numbers) of the rotational spectrum of HI is 13.2 cm-1, which corresponds to B = AE0–1/2 = 6.6 cm-1. The principal isotope of Iodine has a mass of 127 amu. From this information, determine: (a) What is the moment of inertia of HI? (b) What is the HI bond length? (c) What is AE0_1 for deuterium iodide?

The force constant for the carbon monoxide molecule is 1,908 N m At 1,000 K what is the probability that the molecule will be found in the lowest excited state? At a given temperature the rotational states of molecules are distributed according to the Boltzmann distribution. Of the hydrogen molecules in the ground state estimate the ratio of the number in the ground rotational state to the number in the first excited...

+V 0V Detector The picture above shows part of a mass spectrometer that can be used to measure molecular charge-to-mass ratios. A charged molecule (orange circle) is ionized and accelerated through an electric potential difference into a region with a uniform magnetic field. Here the magnetic field points out of the screen. The field makes the positively charged molecules undergo circular motion as shown. By adjusting the voltage difference between the plates, one can change the radius of curvature of...
