Question

Order these spectroscopy techniques by typical sample preparation complexity for solids (least to most). A. Raman with microscope
B. XPS
C. mid-IR transmission (KBr pellet)
Choose the correct answer from the options given below :

• A. A $<$ B $<$ C
• B. B $<$ C $<$ A
• C. B $<$ A $<$ C
• D. A $<$ C $<$ B

Hint:

Least prep: Raman → Moderate: XPS → Most: IR (KBr pellet).
