Thienothiophene and sexithiophene are conjugated molecules used in printed organic electronics. A chlorobenzene solution of equal concentrations of the two molecules was prepared and its absorbance was recorded with a 0.01 cm sample cell to give 0.88 % transmittance (T) at 400 nm. Calculate the concentration of each of the molecules given that the molar absorption coefficient of the thienothiophene is 23,000 L.mol-1cm-1 and the sexithiophene is 34,000 L.mol-1cm-1. Remember that absorbance is additive.

An impurity in water has an extinction coefficient of 3.45 * 103 M-1 cm-1 at 280 nm, its absorption maximum(A Closer Look, p. 576). Below 50 ppb, the impurity is not a problem for human health. Given that most spectrometers cannot detect absorbances less than 0.0001 with good reliability, is measuring the absorbance of a water sample at 280 nm a good way to detect concentrations of the impurity above the 50-ppb threshold?

A student needs to prepare a ¹H NMR sample for an organic compound soluble in chloroform (CHCI3). The student cannot use CHCI 3 as the solvent for the sample, but rather uses deuterated chloroform (CDC13) because: O CDC13 is more polar. O CDC13 will not produce a signal in the ¹H NMR spectrum, and therefore will not mask the signals of the compound. O The compound will be more soluble in CDCI 3. O CDC13 is cheaper than CHCI 3.
