For CARS, which statement is not true regarding its advantages?
a) Contrast signal based on vibrational characteristics, no need for fluorescent tagging.
b) Stronger signals than spontaneous Raman.
c) Suffers from fluorescence interference, because CARS signal is at high frequency.
d) Faster, more efficient imaging for real-time analysis.
e) Higher resolution than spontaneous Raman microscopy.

Using a cell of known pathlength b = 1.25115 x 10-3 cm, a water absorption spectrum was measured. The band at 1645 cm-1, assigned to the O-H bending, showed an absorbance, A, of 1.40.
a) Assuming that water density is 1.00 g/mL, calculate the water molar concentration c (hint: M= mole/L)
b) Calculate the molar absorptivity, a, of the 1645 cm-1 band
c) The transmitted light, I, can be written as I= Ioexp(-xb), where x is the absorption coefficient (sometimes designated as alpha), Io is the input light, and b is the cell pathlength. Prove that x= (ln10)*x*c
d) Calculate x for the 1645 cm-1 band
