The 13C NMR spectrum of ethanoic acid (acetic acid) shows a quartet centred at δ = 21 with a splitting of 130 Hz. When the same spectrum is recorded using proton decoupling, the multiplet collapses to a single line. Another quartet, but with a much smaller spacing, is also seen centred at δ =178; this quartet collapses when decoupling is used. Explain these observations.
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?
