Discovering Constant B in Rotational Spectroscopy of CO Molecule"

Click For Summary

Discussion Overview

The discussion revolves around determining the rotational constant B for the CO molecule using its microwave spectrum. Participants explore methods for calculating B under different conditions, specifically whether the molecule behaves elastically or inelastically.

Discussion Character

  • Homework-related, Technical explanation

Main Points Raised

  • One participant inquires about the process for finding the constant B, indicating uncertainty regarding the conditions of elasticity.
  • Another participant questions whether to start with the moment of inertia or the spectrum itself, expressing difficulty in determining the distance R needed for calculations.
  • A request for formulas relevant to both elastic and inelastic cases is made, along with a suggestion to fit the spectrum to these formulas.
  • There is a repetition of the request for formulas, with a participant seeking clarification on whether equations are being referred to.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as participants express differing levels of understanding and approach regarding the methods to calculate the constant B.

Contextual Notes

Participants mention challenges related to the moment of inertia and the need for specific distances, indicating potential limitations in their current understanding or available data.

So I am given a rotational microwave spectrum of a molecule (CO specifically) and I have to find the constant B if it's not elastic , the constants B and Dj if it is elastic. Anyone know how to do that? :frown:

Do I start by finding the moment of inertia? or do I use the spectrum? I have a problem with the moment of inertia I can't find the distance R...
 
What are formulas for both cases? Have you tried to fit the spectrum to them?

sorry english is not my native language and I'm not sure i understand what you're saying... you mean the equations?
 
Yes.
