Round 3: Tossup 4

Shot noise in the detector of this technique induces a standard deviation in its main output T proportional to the square root of T times T plus one. In this technique, using the octant rule to predict the Cotton effect can distinguish enantiomers (-5[2])through circular dichroism. Potassium dichromate is a calibration standard for this technique. (-5[1])Using this technique, (-5[1])the purity of a DNA or RNA mixture is characterized by the 260 (10[1])to 280 ratio. This technique’s input value for a highly conjugated (10[1])compound can be estimated by applying the Woodward–Fieser rules. This technique’s primary measurement equals the product of concentration, the path length of a cuvette, (10[1])and the molar (10[1])extinction coefficient, by the Beer–Lambert law. For 10 points, name this technique that tracks the absorbance of a sample with respect (10[1])to low wavelengths. ■END■ (10[1]0[2])
