Quiz 2 - Advantages and Disadvantages of FTIR

--------------------------------------------------------------------------------
Question 1
What is the Fellgett advantage of FTIR?
a. Increased throughput
b. FTIR is more infrared efficient than dispersive spectroscopy.
c. All spectral elements measured at the same time
d. FTIR is a simpler technique, and therefore easier to use.
