Though produced by Agilent, a popular line of devices used for this technique is still named for Cary Instruments. Aromatic substitutions often cause readings produced by this technique to undergo shifts prefixed “hypso” and “batho.” The existence of secondary bands in spectra generated by this technique is typically (15[1])used to identify the presence of hyperconjugated molecules in a sample. In a method used to predict this technique’s results, heteroannular dienes (“dai-eenz”) are assigned a base value of (*) 214 for one quantity. That quantity obtained from this technique, whose results can be predicted via the Woodward-Fieser rules, is found by calculating the log ratio (-5[1])of the intensity of light hitting and leaving a cuvette; that calculation (10[1])is based on Beer’s law. (10[1])For 10 points, name this form of spectroscopy used to measure a sample’s absorbance to two forms of light. (10[1])■END■ (10[1])
