1. A certain proton NMR spectrum (recorded on a 400 MHz NMRspectrometer) consists of one singlet and one doublet. The singlethas a chemical shift of 5.0 ppm. The doublet is 2600 Hz upfieldfrom the singlet. Which one of the following statements iscorrect?
A) The chemical shift of the doublet (on the delta scale) ispositive
B) The chemical shift of the doublet (on the delta scale) isnegative
2. Which one of the following statements is correct?
A) The electromagnetic radiation used in IR spectroscopy ishigher in energy than that used in X-ray crystallography
B) The electromagnetic radiation used in IR spectroscopy islower in energy than that used in X-ray crystallography
