Hello!

My question is regarding IR spectra of inorganic species. I did both for a compound, but they are significantly different from each other. I know it is not the oil's fault since it is not its range.
I was wondering what factors can play a role here.
Is it the fact that there is much more  interactions between particles of my substance when it is in the solid state, rather than with solvent being all around in the solution. Or does it not influence my result.

I will appreciate your *delete me*

Cheers,

Can you elaborate on what these differences are?

Are you sure the differences are not just the nujol peaks (google image search for the IR spectrum of nujol)?

Sample prep can be an issue.  Many inorganic materials absorb at the low end of the
IR spectrum.  If you are doing a prep, try KBr cells or a KBr press.  Sodium choride
will absorb much at the low end.

You also have no peaks from nujol.

Good luck

Thanks for the answers.
I repeated the tests and this time everything seems to work properly.
Thanks!
