Analysis of the results of this technique may include plotting the nominal and defect forms of a quantity named for Kendrick. In this technique, cyclohexene and its derivatives characteristically undergo the retro-Diels–Alder reaction. The (15[1])output of this technique may display skewing due to changes in the analyte’s concentration over the scanning time. In this technique, compounds containing carbonyl groups may undergo the (*) McLafferty rearrangement. The strongest signal in this technique, whose intensity is set to 100, (10[1])is called the base peak. This technique often obtains M+1 signals due to carbon-13. In this technique, the analyte is ionized and then deflected by a magnetic field. For 10 points, name this analytical technique that separates molecular fragments by their ratio of a namesake quantity (-5[1])to charge. ■END■ (0[1])
