Flame atomic absorption spectrophotometry: can it detect anions?

Your teacher is partially correct. Flame AAS is more feasible for metals, almost all of them. Mention to your teacher that flame AAS does not know whether you are introducing anions or cations in the ...

How to find the infrared absorption spectrum of O2 and N2?

There is a good reason for not being able to find the mid-IR absorption spectra of nitrogen and oxygen. Their vibrations are infrared inactive. Infrared absorption peaks are observed when there is a ...

Rotational spectroscopy of diatomic molecules

In a classical way, think of the radiation as an oscillating dipole. If a molecule also has a dipole and it rotates or vibrates then this is also an oscillating dipole. It is a property of dipoles ...

FTIR Spectra: Did I synthesize ethyl gallate from gallic acid?

The short answer: consider a technique complementary to IR spectroscopy, for instance $\ce{^1H}$-NMR spectroscopy. Your have good luck, as the public AIST spectral database holds records of IR spectra ...

FTIR Spectra: Did I synthesize ethyl gallate from gallic acid?

In determining whether you successfully synthesized ethyl gallate from your gallic acid precursor, let's go over what differences between the two you should expect in your spectra. Ethyl gallate (...
