How do I measure the binding energy of a molecule?

Click For Summary
SUMMARY

The discussion centers on measuring the binding energy of the HeO molecule, which is 11.2 cm-1. A magnetic field of 4 T was utilized to disrupt the van der Waals forces holding the molecule together. The binding energy represents the work required to separate the molecule, and various experimental methods exist to determine this energy. The conversation also touches on the equation for binding energy, specifically for gas molecules like hydrogen, and the distinction between measurement and calculation.

PREREQUISITES
  • Understanding of van der Waals forces
  • Familiarity with binding energy concepts
  • Knowledge of magnetic fields and their effects on molecular structures
  • Basic principles of spectroscopy for measuring energy
NEXT STEPS
  • Research methods for measuring binding energy in molecular physics
  • Explore the use of magnetic fields in molecular dissociation
  • Learn about the calculation of dissociation energy using the equation EBinding=ΔE≈3BμB/2(MMax−MMin)
  • Investigate spectroscopy techniques for determining molecular binding energies
USEFUL FOR

Researchers in molecular physics, chemists studying molecular interactions, and students interested in the experimental measurement of binding energies will benefit from this discussion.

The authors probably looked it up in a big book (or online).
The binding energy is the work needed to separate the molecule... there are lots of ways of figuring that out experimentally.
I don't know the specific methods used for HeO... look at how the molecule is formed. But it looks like the dissociation energy should be straight forward to get.
What is the concern here?
 
Thank you for the response! I was wondering what this equation would like for other gas molecules (Eg. hydrogen):

EBindng=ΔE≈3BμB/2(MMax−MMin)

I didn't understand how to measure the binding energy for an equation like this, but I may have found a solution in this video describing how to calculate the wavelength of light required to break a chemical bond:



Please let me know if I'm on the right track!
 
There is a difference between measuring something and calculating it.
