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 molecule rotation as "rotation on a sphere". Calculate the rotational energy difference, in cm-1, between the l=3 and l=4 energy level in a hydrogen bromide-79 molecule.

Moment of Inertia To find the moment of inertia of different objects and to observe the changes in angular acceleration relative to changing moments of inertia. To also learn how to use calipers in making precise measurements The momentum of inertia of an object is calculated as I=∑mr^2 If the object in question rotates around a central point, then it can be considered a "point mass", and its moment of inertia is simply,  I=mr^2 where r is from the central point...

The two nuclei in the carbon monoxide (CO) molecule are 0.1128nm apart. The mass of the carbon atom is 1.993x10-26kg and the mass of the oxygen atom 2.656x10-26kg. Because the two atoms have different masses, the center of gravity of the molecule is NOT half-way between the atoms. 1. Calculate the location of the center of gravity of the CO molecule and deduce the distances rC and rO of, respectively, the Carbon atom and the Oxygen atom from the center...

MOMENT OF INERTIA LAB Apparatus Only (P3) With Masses (P4) With Block (P5) Setup You have a T-shaped apparatus that can spin about a vertical axis. One end of a light string is wrapped around the vertical shaft of the apparatus. The other end passes over a pulley and has a known mass hung from it to establish tension in the string. By measuring the acceleration of the hanging mass, the rotational inertia of the apparatus can be determined. Specifically,...

1. Consider the diatomic nitrogen molecule N2, which is rotating in the xy plane about the z axis passing through its center, perpendicular to its length. The mass of each nitrogen atom is about m= 2.40×10-26 kg, and at room temperature, the separation between the two-nitrogen atom is d = 1.32×10-10 m. A typical speed of a molecule is 4.60×1012 rad/s. If the nitrogen molecule is rotating with this angular speed about the z axis, what is its rotational kinetic...

Please answer all parts. Thank you! 1. Explain the correspondence that lets us easily translate between linear motion and rotational motion. What are the linear analogues of the rotational quantities we have discussed in lecture i.e. angle, angular velocity, angular acceleration and moment of inertia? Where does the correspondence seem to fail? 2. Explain, in words, how we know that a freely spinning asteroid in space is rotating about an axis that passes through its center of mass? 3. You...
