For Raman spectroscopy/imaging, which statement is not true regarding its disadvantages?
a) Limited spatial resolution.
b) Short integration time.
c) A one-dimensional technique.
d) Weak signal, only 1 in 108 incident photons is Raman scattered.
e) Fluorescence interference.
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. (Please provide a full derivation of the equation for x from the equation for I).
d) Calculate x for the 1645 cm-1 band
