As a first approximation to the description of the rotation of a 1 H127I molecule, we can imagine an 1 H atom orbiting a heavy, stationary 127I atom at a distance r = 160 pm, the equilibrium bond distance. Calculate the following: The degeneracy of these four levels (from 2l + 1).

1.Consider the rotation of a hydrogen bromide-79 molecule. What is the moment of inertia in kg m2 of hydrogen bromide-79? Isotope masses to three decimal places are taken from NIST and bond lengths from wikipedia. Use the isotope mass, not the average mass. 2.Next, model the rotation of hydrogen bromide-79 as a "particle on a ring". Calculate the rotational energy difference, in cm-1, between the ml=3 and ml=4 energy levels in a hydrogen bromide-79 molecule. 3.Now model the hydrogen bromide-79...

Positronium is an exotic form of matter formed by an electron and a positron (a positively charged electron) orbiting around a common center at a distance of 1.06 D (from each other, not from the center). We will assume that the system rotates in a way approximated by the rigidrotor model. Calculate the following: A. The first four energy levels associated to the rotation (in three dimensions) for this system. B. The first four possible values of the angular momentum...

Question 1 In this question we undertake the Hydrogen Atom Model, developed in 1913 by Niels Bohr. a) Write the electric force reigning between the proton and the electron, in the hydrogen atom, in CGS system. Then equate this force, with the force expressed in terms of mass and acceleration, to come up with Bohr's equation of motion. Suppose that the electron orbit, around the proton, is circular. Use the following symbols, throughout. e: proton's or electron's charge intensity(4.8x 10-8...

The wavelengths of spectral lines depends to some extent on the mass of the nucleus. This occurs because the nucleus is not an infinitely heavy mass that remains stationary. In fact, in reality, both the nucleus and the electron orbit about their common center of mass. It can be shown that a system of this type is entirely equivalent to a single object with a mass μμ (called the Reduced Mass) that orbits about the location of the nucleus at...
