Problem

Which of the following statements regarding NMR spectroscopy is wrong?

a) NMR signals towards the left of the spectral chart correspond to larger chemical shifts.

b) Chemical shifts are larger when the frequencies of the radiation which induces the nuclear transitions are higher.

c) Chemical shifts are larger when shielding effects are greater.

d) A hydrogen signal splits into n+1 peaks by spin-spin coupling when the number of equivalent hydrogen atoms on adjacent atom(s) is n, and no other neighbouring atoms are involved.
