If you observe a peak around 1700 cm⁻¹ in the FT-IR spectrum, what functional groups could it correspond to, and how would you confirm which one is present?

Explain the difference between the O-H stretch for alcohols and carboxylic acids in FT-IR spectra. How would you distinguish between the two?

If two oils have very similar ester carbonyl peaks, the fingerprint region and subtle unsaturation features may still allow discrimination.

What is the likely identity of an oil sample showing strong C=O at 1743 cm⁻¹, strong alkyl C–H, and cis-alkene =C–H bend at 720 cm⁻¹?

DF for transferring Va into Vf is DF = [A]/[B].

In FTIR, the sample absorbs infrared radiation in the range from 4000 to 400 cm-1, and this absorption gives rise to characteristic vibrational frequencies.

FTIR spectroscopy measures the absorption of __________ radiation, typically between the wavenumber range of 4000 to 400 cm-1.

If a wavelength calibration fails, you should check the ______ introduction system.

Running plasma without the spray chamber/nebulizer gas supply connected can damage the torch.

Once I create my account on LingroLearning, I will have access to the electronic version of the book (eText). Therefore, I am not required to purchase a hard copy of the textbook. (Hint: A hard copy of the textbook is not required!)
