1. Explain one way in which the ATR spectrum of octanoic acid is different from the transmission mode spectrum.

2. How does ATR gives a more accurate result than Transmission FTIR?

3. Explain why the baseline (IR spectrum) is not 100% T for the KBr pellet and the Nujol mull spectra of benzoic acid.

Expert Solution

Octanoic Acid is a soaked medium-chain unsaturated fat with a 8-carbon spine.

ATR creates more solid outcomes than Transmission spectra.

The recurrence of transmission and ATR estimation varies essentially.

Impact of obstruction edges can be found in Transmission spectra(larger flag to commotion proportion).

All examples are put undiluted in ATR estimation.

ATR relies on the refractive list of the example,

so can give estimations of a large portion of the samples(organic, inorganic) as their refractive list lies in that appropriate range.

ATR (Attenuated absolute reflection) is a join utilized rather than readiness KBr plate part.

It's increasingly proficient and gives a progressively exact outcome, low flag to clamor proportion .

additionally little example needs to make broke down, just 0.5-1 micron.

On the off chance that the outside of the reference test is rougher and more bended than the example,

the range benchmark demonstrates a transmittance surpassing 100%T.
