Select ALL troubleshooting steps for a flat/weak spectrum on ATR.

Select ALL cases where you should re-run an ATR measurement.

The functional group associated with a broad O-H stretch between 3000-2500 cm-1 in FT-IR spectra is ____________.

The FT-IR spectrometer can only analyze solid samples, not liquids.

Peaks in the fingerprint region (below 1500 cm⁻¹) are generally used to identify specific functional groups like alcohols and ketones.

What is the primary purpose of the MP-AES instrument?

A spectrum with aromatic bands ~1600/1500 cm^-1 AND a strong carbonyl ~1715 cm^-1 most strongly suggests:

How can you differentiate between alcohol and carboxylic acid functional groups in an FT-IR spectrum?

Using FT-IR, you analyze an unknown organic liquid and identify a strong peak at 1740 cm-1 and a broad peak around 3300 cm-1. What functional groups are likely present, and what is the possible identity of the unknown?

What are the key steps in preparing a sample for ATR analysis in FTIR?
