Spring constant of diatomic molecule PbO???
Spring constant of diatomic molecule PbO???
(OP)
Hello,
I have a problem in relation to the vibration of a diatomic molecule (PbO), but it has been too long ago since I last had chemistry and physics...
If I look at PbO as a system of 2 masses and 1 spring (a harmonic oscillator), is there a way to know the "spring constant" of this diatomic molecule, for example based on the difference in "Electronegativity" between Pb and O (...or on something else)? I want to calculate the eigenfrequency and energy stored in this diatomic molecule.
Thanks a lot !!

RE: Spring constant of diatomic molecule PbO???
According to Lange's Handbook of Chemistry the PbO molecule decomposes on boiling at 1472oC.

So if it decomposes at 1472°C, can I calculate the spring constant in some way please?
Thanks in advance!

Could you ps tell more about your problem and application?
Wouldn't it simpler to measure it?
I assume there is a huge difference if it is one mol.
thick layer or in bulk.
