Question

Though produced by Agilent, a popular line of devices used for this technique is still named for Cary Instruments. Aromatic substitutions often cause readings (-5[1])produced by this (15[1])technique to undergo shifts prefixed “hypso” and “batho.” (15[1])The existence of secondary bands in spectra generated by this technique is typically used to identify the presence of hyperconjugated molecules in a sample. In a method used to predict this technique’s results, heteroannular (-5[1])dienes (“dai-eenz”) are assigned a base value of (*) 214 for one quantity. That quantity obtained from this technique, (10[1])whose results can be predicted via the Woodward-Fieser rules, is found by calculating (10[1])the log ratio of the intensity of light hitting and leaving (0[1])a cuvette; that calculation is based on Beer’s law. For (10[1])10 points, (-5[1])name this form of spectroscopy used to measure a sample’s absorbance to two forms of light. ■END■ (10[1]0[1])
