13C NMR spectroscopy provides valuable information about the environments of a molecule's carbon atoms. Since carbon atoms are often connected to hydrogen atoms, which could split the carbon signal through spin-spin coupling, the coupling between C and H is often "turned off" through the use of broadband decoupling, causing each C signal to appear as a singlet. Draw an isomer of C5H11Cl that would be expected to have four resonances in its 13C NMR spectra.

The beer-lambert law is A = εlc, where A is the absorbance, ε is the molar extinction coefficient, l is the path lengh in cm and C is the concentration. The beer lambert law can be expressed in the form of y=mx + b, where A is y, and C is x.What is b and how is it used to calculate the final absorbance?
