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 through circular dichroism. Potassium dichromate is a calibration standard for this technique. Using this technique, the purity of a DNA or RNA mixture (10[1])is characterized by the 260 to 280 ratio. (10[1])This technique’s input value for a highly conjugated 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, 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 to low wavelengths. ■END■
