Microwave Spectroscopy - Obtaining info when isotope absorptions are known

Click For Summary
SUMMARY

This discussion focuses on using known isotope absorptions to derive internuclear distances in diatomic molecules through microwave spectroscopy. The key formula required is the rotational energy levels of diatomic molecules, which can be utilized alongside the masses of hydrogen, deuterium, and iodine obtained from the periodic table. Participants emphasize the importance of understanding the relationship between isotopic mass differences and rotational transitions to extract the necessary molecular parameters.

PREREQUISITES
  • Understanding of microwave spectroscopy principles
  • Familiarity with rotational energy levels of diatomic molecules
  • Knowledge of isotopic mass differences
  • Ability to interpret data from the periodic table
NEXT STEPS
  • Study the derivation of rotational energy levels for diatomic molecules
  • Learn about the impact of isotopic substitution on molecular spectra
  • Research methods for calculating internuclear distances from spectroscopic data
  • Explore advanced topics in molecular spectroscopy techniques
USEFUL FOR

Students and researchers in physical chemistry, spectroscopists, and anyone interested in molecular structure analysis through microwave spectroscopy.

Heres the question
[PLAIN]http://img213.imageshack.us/img213/2669/16772870.jpg
I know that I'm supposed to derive these values from the fact that I know the absorptions of 2 different isotopes of the diatomic molecule but I don't know how to go about doing it. I can obtain the masses of hydrogen, deuterium and iodine from the periodic table but I don't know how I can use this data to get the internuclear distances.

You need the formula for the rotational energy levels of diatomic molecules.
